| Description | The TPS71202DRCR is a high-performance dual adjustable low-dropout linear voltage regulator (LDO) from Texas Instruments. Designed for noise-sensitive analog, RF, and mixed-signal applications, the device integrates two independent 250mA linear regulators with ultra-low output noise, high power-supply rejection, fast transient response, and independent enable control in a compact 3 × 3mm VSON package. The TPS71202 belongs to the TPS712 dual-output LDO regulator family, which is optimized for applications requiring multiple low-noise supply rails with minimal PCB area and low power consumption. The device provides two independently adjustable outputs, allowing designers to generate different regulated voltages from a common input supply. Each regulator channel supports a maximum continuous output current of 250mA, providing a combined output capability of 2 × 250mA. The two channels can power separate analog and digital circuits, RF subsystems, sensor interfaces, or other electronic components requiring independently controlled voltage rails. The TPS71202 is the dual-adjustable version of the TPS712 family. Both outputs can be programmed through external feedback resistor networks over a nominal voltage range of 1.2V to 5.5V, subject to the available input voltage and dropout requirements. The regulator operates with an input supply voltage of up to 5.5V, making it suitable for systems powered from common 3.3V and 5V supply rails. The required input voltage must remain sufficiently above the programmed output voltage to maintain regulation under the intended load conditions. A major advantage of the TPS71202DRCR is its very low dropout voltage. Each regulator provides a typical dropout voltage of approximately 125mV at 250mA, enabling efficient regulation when the input voltage is only slightly higher than the required output voltage. The low-dropout architecture makes the device particularly useful in battery-powered systems and point-of-load power applications. By minimizing the voltage difference required between input and output, the regulator can extend usable battery operating time and reduce unnecessary power dissipation. The TPS71202DRCR provides excellent power-supply rejection ratio (PSRR), with typical performance of approximately 65dB at 10kHz. This characteristic helps suppress ripple and unwanted noise from upstream switching converters, battery supplies, and other power sources. High PSRR is particularly important when powering RF receivers, RF transceivers, precision analog circuits, ADCs, DACs, and sensitive sensor interfaces. By reducing supply-borne interference, the TPS71202DRCR can help improve overall analog signal integrity and system performance. The device also features ultra-low output voltage noise, with a typical noise level of approximately 32µVRMS under specified operating conditions using a 0.01µF noise-reduction capacitor and a 2.8V output configuration. The low-noise architecture makes the TPS71202DRCR particularly suitable for RF and mixed-signal electronics where supply noise can affect receiver sensitivity, oscillator stability, converter accuracy, or overall signal quality. Each regulator includes a dedicated noise-reduction and bypass function that can be implemented using an external capacitor. Appropriate bypass capacitor selection helps reduce reference noise and optimize the regulator's output-noise characteristics. The TPS71202DRCR supports fast startup, with a typical startup time of approximately 60µs when using a 0.001µF bypass capacitor under the specified test conditions. This rapid response supports systems that frequently enable and disable individual power rails. Both regulator channels include independent enable inputs, allowing each output to be controlled separately. This enables flexible power sequencing, selective subsystem shutdown, dynamic power management, and reduced system power consumption during standby or sleep modes. When both regulator channels are enabled, the TPS712 family typically consumes approximately 300µA of quiescent current. When the device is placed in standby mode with both channels disabled, typical supply current is reduced to less than 0.3µA. This low standby-current capability is especially useful in battery-powered electronics, portable communication equipment, handheld instrumentation, and embedded systems that must minimize power consumption when inactive. The TPS71202DRCR is designed to provide excellent line and load transient response. Its internal control architecture responds quickly to changes in input voltage and output current, helping maintain stable regulated voltages during dynamic operating conditions. Each regulator is stable with a compact 2.2µF ceramic output capacitor, allowing the device to be implemented using low-cost, low-ESR multilayer ceramic capacitors. This reduces external component count and enables compact power-supply layouts. The dual-channel architecture is particularly beneficial in applications requiring separate supply rails for analog and digital circuitry. Designers can configure the two outputs for different voltage levels while maintaining independent enable control and low-noise regulation. The TPS71202DRCR incorporates independent current-limit protection for each regulator channel. If one output experiences an overload or short-circuit condition, its current-limiting circuitry helps prevent excessive output current. The device also includes thermal shutdown protection, which protects the regulator against excessive junction temperature. These protection features improve system robustness during abnormal operating conditions and help reduce the risk of damage caused by overloads or excessive power dissipation. The TPS71202DRCR is specified for an operating junction temperature range of -40°C to +125°C. This wide temperature range makes it suitable for industrial electronics, embedded computing, instrumentation, communication equipment, and other applications requiring reliable power regulation. The device is particularly suitable for RF and wireless communication systems, where low-noise regulated supplies are essential for maintaining signal quality. Typical applications include RF transceivers, wireless LAN modules, portable communication devices, and other noise-sensitive electronic subsystems. The TPS71202DRCR can also provide local power regulation for microcontrollers, DSPs, FPGAs, ASICs, and embedded processors. The two adjustable outputs can be configured to supply separate voltage domains, provided the required current and voltage levels remain within the device's operating limits. In precision measurement applications, the regulator can supply analog-to-digital converters, digital-to-analog converters, operational amplifiers, and sensor signal-conditioning circuits. Its high PSRR and low output noise help reduce interference introduced through the power supply. The TPS71202DRCR is supplied in a compact 10-pin VSON package, identified by Texas Instruments package code DRC. The package measures approximately 3.0 × 3.0 × 1.0mm and occupies only 9mm2 of PCB area. The package includes an exposed thermal pad that improves heat transfer into the PCB. Proper thermal pad connection, copper area, grounding, and placement of input and output capacitors are important for achieving reliable thermal performance and minimizing output noise. The R ordering suffix identifies the large tape-and-reel packaging configuration. The TPS71202DRCR is supplied in a standard manufacturer package quantity of 3000 devices per reel, making it suitable for automated SMT assembly and high-volume electronics manufacturing. The TPS71202DRCR is RoHS and REACH compliant and uses a lead-free NiPdAu terminal finish. The device has a moisture sensitivity classification of MSL 2 with a maximum specified peak reflow temperature of 260°C. The combination of two independently adjustable 250mA LDO outputs, 1.2V to 5.5V output adjustment, 125mV typical dropout, 65dB PSRR at 10kHz, 32µVRMS typical output noise, 60µs fast startup, independent enable inputs, low standby current, ceramic capacitor stability, independent current limiting, thermal shutdown, and compact VSON-10 packaging makes the TPS71202DRCR a versatile solution for dual-rail low-noise power management. The TPS71202DRCR is widely used in RF transceivers, wireless communication equipment, cellular and cordless phones, portable electronics, wireless LAN modules, handheld instruments, data acquisition systems, ADC and DAC power supplies, precision analog circuits, sensor interfaces, DSP and FPGA power management, ASIC power supplies, embedded processors, industrial instrumentation, digital cameras, audio electronics, battery-powered equipment, and general-purpose dual-output low-noise voltage regulation applications. |
