The input voltage range of 4.5V to 55V makes it suitable in 12V to 48V power rails and in high-voltage battery packs. A low UVLO at shutdown of 2.4V makes it adequate for cold cranking conditions in automotive applications. The MCP1792/3 comes in two standard fixed output voltage versions: 3.3V and 5.0V. The regulator output is stable with 2.2 µF.
