Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for AS1351

AS1351

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

The AS1351 is a dual CMOS low-dropout voltage regulator housed in a 12-pin QFN 3x3mm package. It features two independent programmable regulators with an output current of 200mA each and a supply range of 3V to 5.5V. The output voltage is adjustable from 1.8V to 3.3V in 0.1V steps via one-time programmable (OTP) functions or factory trimming. Key electrical parameters include a dropout voltage of 0.2V at 200mA, a shutdown current of ≤1µA, and a typical supply current of 125µA. Power supply rejection ratio reaches 70dB at 1kHz and 40dB at 100kHz.
