LT1762EMS8#PBF

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

The LT1762EMS8#PBF is a micropower, low noise, low dropout regulator from Analog Devices Inc. It supplies 150mA of output current with a typical dropout voltage of 270mV. Designed for battery-powered systems, it features a low quiescent current of 25µA that remains stable in dropout. The device offers fixed output voltages of 2.5V, 3V, 3.3V, and 5V, or an adjustable version with a 1.22V reference. Output noise drops to 20µVRMS over a 10Hz to 100kHz bandwidth with a 0.01µF bypass capacitor. It operates within an input voltage range of 1.8V to 20V and includes reverse battery protection, current limiting, and thermal limiting.
