| Description | The TPS7B6933QDCYRQ1 is an automotive-qualified low-dropout linear voltage regulator (LDO) from Texas Instruments, designed for high-voltage and low-quiescent-current power supply applications. The device combines a wide input voltage range, fixed 3.3V output, low standby current, and integrated protection features for reliable operation in automotive and industrial electronic systems. The TPS7B6933QDCYRQ1 provides a fixed 3.3V regulated output with a maximum output current capability of 150mA. It is particularly suitable for powering microcontrollers, sensors, communication interfaces, monitoring circuits, and other low-power electronic loads that require a stable 3.3V supply. The regulator supports a wide 4V to 40V input voltage range and is designed to withstand input transients of up to 45V. This high input voltage capability makes the device suitable for automotive off-battery applications where the supply voltage can vary significantly during normal vehicle operation and transient conditions. One of the key features of the TPS7B6933QDCYRQ1 is its extremely low quiescent current of approximately 15µA typical at light loads. The quiescent current remains very low even when the regulator is continuously connected to the battery, making the device well suited for always-on and standby electronic systems. The low operating current is especially beneficial in battery-powered automotive systems where electronic modules can remain active while the ignition is switched off. Reducing standby current helps minimize battery drain during extended parking or storage periods. The device provides a typical dropout voltage of approximately 450mV at 100mA load current. Low-dropout operation allows the regulator to maintain a stable output voltage even when the input supply approaches the required output voltage, improving the usable operating range of the power source. The TPS7B6933QDCYRQ1 is stable with low-ESR ceramic output capacitors from 2.2µF to 100µF. Ceramic capacitor compatibility allows designers to implement compact, reliable, and cost-effective power supply filtering without requiring specialized high-ESR output capacitors. The regulator integrates short-circuit and overcurrent protection to protect the device and downstream circuitry during excessive load or fault conditions. These protection functions improve system robustness in automotive environments where wiring and load faults can occur. An integrated thermal shutdown function protects the regulator against excessive junction temperature. If device temperature rises beyond the internal protection threshold, the regulator limits operation to help prevent permanent damage caused by excessive thermal stress. The TPS7B69-Q1 family is AEC-Q100 qualified for automotive applications. The TPS7B6933QDCYRQ1 supports an ambient operating temperature range of -40°C to +125°C, enabling reliable use in automotive electronic modules exposed to wide environmental temperature variations. The combination of a high input voltage rating and low quiescent current makes the device particularly useful for direct automotive battery-connected power supplies. It can provide a continuously regulated low-voltage rail for circuitry that must remain powered when other sections of the vehicle electronics are inactive. The fixed 3.3V output eliminates the external feedback resistor network required by adjustable regulators. This reduces external component count, saves PCB space, and eliminates output-voltage errors associated with external feedback resistor tolerances. The TPS7B6933QDCYRQ1 is supplied in a 4-pin SOT-223 package, identified by Texas Instruments package code DCY. The SOT-223 package provides a practical balance between compact PCB footprint and thermal performance for 150mA linear-regulator applications. The RQ1 ordering designation identifies the automotive-qualified tape-and-reel version. Texas Instruments supplies the TPS7B6933QDCYRQ1 in a standard package quantity of 2500 pieces per reel, suitable for automated high-volume surface-mount assembly. The combination of 4V to 40V operating input range, 45V transient capability, fixed 3.3V output, 150mA output current, 15µA typical quiescent current, low-dropout operation, AEC-Q100 automotive qualification, short-circuit protection, overcurrent protection, and thermal shutdown makes the TPS7B6933QDCYRQ1 a robust power management solution for automotive always-on electronics. The TPS7B6933QDCYRQ1 is widely used in automotive body electronics, battery-connected control modules, electronic control units, gateway modules, automotive sensors, infotainment standby circuits, remote keyless entry systems, alarm systems, telematics modules, dashboard electronics, automotive microcontroller power supplies, always-on circuits, industrial control systems, battery monitoring equipment, and other high-voltage low-power electronic applications. |
