Description for the TPS7E82
The TPS7E82 low-dropout (LDO) linear voltage regulator is a low quiescent current device and supports wide input voltage range from 3V to 40V. The wide output range is from 1.2V to 38V for the adjustable configuration, 1.8V to 12V for the fixed configuration, and a load current of up to 300mA 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 TPS7E82 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 TPS7E82 supports a low dropout of typically 900mV at 300mA of load current. The device has built-in protection mechanism for over-current, over-temperature and over-power delivery for reliable operation of the LDO. The TPS7E82 is stable with an output capacitor range of 4.7µF to 100µF.
