MCP1792T-3302H/CB General Description

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 ideal 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 2 standard fixed output-voltage versions: 3.3V and 5.0V. The regulator output isstable 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, while delivering a maximum output current of 100 mA.
