MCP1801T-5002I/OT

MCP1801T-5002I/OT is a CMOS low dropout (LDO) voltage regulator that can deliver up to 150mA of current while consuming only 25µA 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. The LDO output is stable with a minimum of 1µF of output capacitance. Ceramic, tantalum, or aluminium electrolytic capacitors can all be used for input and output. The overcurrent limit with the current foldback provides short-circuit protection. Applications include battery-powered devices, battery-powered alarm circuits, smoke detectors, CO2 detectors, pagers and cellular phones, wireless communications equipment, smart battery packs, low quiescent current voltage reference, PDAs, digital cameras, microcontroller power, solar-powered instruments, consumer products, battery-powered data loggers.
