低静态电流LDO Low Quiescent Current LDO
General Description
The MCP1700 is a family of CMOS low dropout LDO voltage regulators that can deliver up to 250 mA of current while consuming only 1.6 µA of quiescent current typical. The input operating range is specified from 2.3V to 6.0V, making it an ideal choice for two and three primary cell battery-powered applications, as well as single cell Li-Ion-powered applications.
