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 es in two standard fixed output voltage versions: 3.3V and 5.0V. The regulator output is stable with 2.2 µF ceramic capacitors. The device is protected from short-circuit events by the current foldback function and from overheating by means of thermal shutdown protection. The MCP1792 is the 3-lead version of the MCP1792/3 device family and the MCP1793 is the 5-lead version, which offers shutdown functionality (SHDN pin). While in shutdown, the quiescent current drops to 2 µA, allowing for lower, overall power consumption. The device itself has a ground current of 100 µA typical, while delivering maximum output current of 100 m A. Note: For other...
