AS1374 Overview
Description
The AS1374 is a low-noise, low-dropout linear regulator with two separated outputs. Designed to deliver 200mA continuous output current at each output pin, the LDOs can achieve a low 120mV dropout for 200mA load current and are designed and optimized to work with low-cost, small-capacitance ceramic capacitors.
Key Features
