MCP1801
150 mA, High PSRR, Low Quiescent Current LDO
Features: Description: The MCP1801 is a family of CMOS low dropout (LDO)
voltage regulators that can deliver up to 150 mA of
current while consuming only 25 ВµA of quiescent
current (typical). The input operating range is specified
from 2.0V to 10.0V, making it an ideal choice for two to
six primary cell battery-powered applications, 9V
alkaline and one or two cell Li-Ion-powered
applications. 150 mA Maximum Output Current
Low Dropout Voltage, 200 mV typical @ 100 mA
25 ВµA Typical Quiescent Current
0.01 ВµA Typical Shutdown Current
