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 outputvoltage 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 curr.
