The TPS7E71 low-dropout (LDO) linear voltage regulator is a low quiescent current device and supports a wide input voltage range of 3V to 30V. The wide output range is 1.2V to 28V for the adjustable configuration, 1.8V to 12V for the fixed configuration, and a load current of up to 150mA is supported. With only a 2.8µA quiescent current at no-load, the device is designed to power microcontrollers and other low-power loads for battery-powered applications.

The TPS7E71 supports very tight DC accuracy of ±1.2% over line, load, and temperature range. The device responds quickly to line and load transients. The low quiescent current (2.8µA typically) during regulation and controlled IQ even in dropout operation (12µA typically in no-load dropout) makes this device designed for battery-powered or always-on systems that require very little idle-state power dissipation.

The TPS7E71 supports a low dropout of typically 450mV at 150mA of load current. The device has a built-in protection mechanism for over-current, over-temperature, and over-power delivery for reliable operation of the LDO. The TPS7E71 is stable with an output capacitor range of 2.2µF to 100µF.
