Description

The MP6402 is a dual-channel, high PSRR linear regulator with reset function.?The outputs range from 0.9V and 3.3V with ?.5% voltage accuracy at both channels by operating from a +2.5V to +5.5V input. OUT2 pin voltage is recommended to be higher than OUT1 pin voltage. Short circuit protection and thermal protection are built in to prevent damage caused by output short circuit and overloading, respectively. A reset circuit is designed to monitor output voltage of channel 2. The?becomes active (low) when OUT2 pin voltage drops below its threshold. To ensure that a complete reset occurs, the? remains active for a pre-set delay time. The delay time is programmable by the user through changing the external capacitor. The MP6402 is available in SOIC8E and 3x3mm TQFN8 packages and is specified for operation TJ from -40?C to +125?C.
