TPS76727QPWP

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The TPS76727QPWP is a fixed-output low-dropout linear regulator providing a nominal 2.7 V output with a maximum continuous current of 1 A. It utilizes a PMOS pass element to achieve an ultralow typical quiescent current of 85 µA, which remains stable across the full load range from 0 mA to 1 A. The device features fast transient response and maintains stability with standard 10 µF low ESR output capacitors. It includes an open-drain power-on reset function with a 200 ms delay and operates within a junction temperature range of -40°C to +125°C.
