MCP1804 - Microchip Technology

MCP1804 28V LDO Regulator

The MCP1804 is a family of CMOS low dropout (LDO) voltage regulators that can deliver up to 150 mA of current while consuming only 50 µA of quiescent current (typical, 1.8V  VOUT  5.0V). The input operating range is specified from 2.0V to 28.0V. The MCP1804 is capable of delivering 100 mA with only 1300 mV (typical) of input to output voltage differential.
