MCP1792 - Microchip

MCP1792 100mA High-Voltage Automotive LDO

The MCP1792/3 family devices are high-voltage, low dropout (LDO) regulators, capable of generating 100 mA output current. 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 .
