Description

The MCP1799 is a high-voltage, low-dropout (LDO)

regulator, capable of generating 80 mA output current.

The input voltage range of 4.5V to 45V makes it ideal in

12V to 36V power rails and in high-voltage battery

packs.

The MCP1799 comes in two standard fixed output-

voltage versions: 3.3V and 5.0V. The regulator output

is stable with 1 µF ceramic capacitors. The device is

protected from short circuit events by the current limit

function and from over heating by means of thermal

shutdown protection.

The device itself has a low ground current of 45 µA

typical, while delivering maximum output current of 80

mA. Without load the device consumes 25 µA typical.
