Device Overview

Summary

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.

For product comparison, please consider: MCP1792
