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.
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.
