DESCRIPTION

The MP8201 is a low voltage, precision,

adjustable shunt regulator. The MP8201 can

operate from 1.2V to 12V where the desired

value is set by external resistors. This wide

dynamic rang, gives the designers outstanding

flexibility in the development of power supplies

and instrumentation. The operating current of

60uA makes the part well suited for battery-

powered portable electronic applications. The

8201 regulates the output voltage from as low as

1.2V. The part has a sharp turn-on characteristic

and a dynamic resistance of less than 1Ω.

The MP8201 is offered in 3-pin SOT23 packages.
