Fast Transient Response, Ultra-Small 250mA Linear Regulator EV Board
The EVQ20056-G-00A evaluation board demonstrates the performance of MPQ20056-18, a low noise, low dropout and high PSRR linear regulator. It operates from a 2.5V to 5.5V input voltage and the output voltage is preset internally at 1.8V.
The EVQ20056-G-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 150μA ground current, making the MPQ20056-G suitable for battery-power devices.

The MPQ20056 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 MPQ20056 suitable for battery-powered devices. Other features include low-power shutdown, short-circuit protection, and thermal protection. The MPQ20056 is available in a 2mm×2mm 8-pin QFN and a 5-pin TSOT23-5 packages
