AS1374-BWLT-285

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

The AS1374-BWLT-285 is a dual low-dropout linear regulator providing two independent 2.85V outputs with a maximum continuous current of 200mA per channel. It operates from an input voltage range of 2V to 5.5V and achieves a dropout voltage of 120mV at full load. The device features ultra-low output noise of 20µVRMS (100Hz to 100kHz) and high power-supply rejection ratio exceeding 85dB at 1kHz. Quiescent current is extremely low at 30µA, and it remains stable with only 1µF ceramic capacitors.
