The TPS7E81-Q1 low-dropout (LDO) linear voltage regulator is a low quiescent current device designed to connect to the battery in the automotive applications and supports wide input voltage range from 3V to 40V. The wide output range is from 1.2V to 38V for the adjustable configuration and 1.8V to 12V for the fixed configuration and up-to 150mA of load current. With only an 2.8µA quiescent current at no-load, the device is a good design for powering always-on components such as microcontrollers (MCUs), gate drivers and controller area network (CAN) transceivers in standby systems.

The TPS7E81-Q1 supports very tight DC accuracy of ±1.2% over line, load and temperature range. The device responds quickly to line and load transients and controls quiescent current in dropout operation.

The TPS7E81-Q1 has built-in protection mechanism for overcurrent, over-temperature and over-power delivery for reliable operation of the LDO. The TPS7E81-Q1 is stable with an output capacitor range of 2.2µF to 100µF.

The TPS7E81-Q1 is available in a 2.0mm × 2.0mm, 6-pin WSON (wettable flank) (DRV-WF), 3.0mm × 3.0mm, 8-pin HVSSOP (DGN) and 2.9mm × 2.8mm, 5-pin SOT-23 (DBV) package for fixed and adjustable outputs.
