Texas Instruments LDO Voltage Regulator 3.3V 150mA SOT-23

Texas Instruments LDO Voltage Regulator 3.3V 150mA is a low-quiescent current, low-dropout (LDO) linear voltage regulator that delivers a stable fixed 3.3V output from an input voltage of up to 10V, with a maximum output current of 150mA.

Overview

The regulator uses a PMOS pass element in place of a traditional PNP pass transistor. This design gives a typical dropout voltage of 300mV at the full 150mA load, which helps maximise usable power in battery-powered designs. Its quiescent current remains at a maximum of 140µA across the 0 to 150mA load range, supporting power-sensitive applications. An ultra-low shutdown mode draws less than 2µA for power savings during standby.
