The Future of Analog IC Technology
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,
2.5V 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.
