MP6402DN-EF-LF

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

The MP6402DN-EF-LF is a dual-channel linear regulator with an integrated reset circuit, manufactured by Monolithic Power Systems. It operates within an input voltage range of +2.5V to +5.5V and provides adjustable output voltages from 0.9V to 3.3V per channel with ±1.5% accuracy. Each channel delivers up to 500mA of output current. The device features high PSRR (60dB at 100Hz) and low noise (15μVRMS). It includes a monitor for Channel 2 with a programmable delay ranging from 2.1ms to 10s via an external capacitor. Built-in protections include short-circuit and thermal shutdown. It is housed in SOIC8E or 3mmx3mm TQFN8 packages.
