MP20056

Low-Noise, High-PSRR, 250mA, Linear Regulator

Active

Datasheet

Description

The MP20056 is a low-dropout linear regulator that supplies up to 250mA current with a 100mV dropout voltage and can operate from 2.5V to 5.5V input. The output voltage is preset at 1.8V or 3.3V for the two different packages. An external resistor divider can adjust the output voltage from 0.8V to 5V.
An internal PMOS pass element allows for a low 150μA ground current, making the MP20056 suitable for battery-powered devices. Other features include low-power shutdown, short-circuit protection, and thermal protection. The MP20056 is available in a 2mm×2mm 8-pin QFN and a 5-pin TSOT23-5 packages.

EV20056-J-00A Evaluation Kit Fast Transient Response, Ultra-Small 250mA Linear Regulator EV Board

The EV20056-J-00A evaluation board demonstrates the performance of MP20056-33, a low noise, low dropout and high PSRR linear regulator. It operates from a 3.7V to 5.5V input voltage and the output voltage is preset internallyat 3.3V.

The EV20056-J-00A can supply up to 250mA of load current, and features current limiting, over temperature protection.

An internal PMOS pass element is used to allow a low 150uA ground current, making the MP20056-J suitable for battery-power devices.
