Microchip Technology MIC5201-5.0YM-TR

Description
The MIC5201 is an efficient linear voltage regulator with very low dropout voltage (typically 17 mV at light loads and 200 mV at 100 mA) and very low ground current (1 mA at 100 mA output). It offers better than 1% initial accuracy with a logic-compatible on-off switching input.
Designed especially for hand-held battery-powered devices, the MIC5201 can be switched by a CMOS enable signal. This enable control may be connected directly to VIN if unneeded. When disabled, power consumption drops nearly to zero. The ground current of the MIC5201 increases only slightly in dropout, further prolonging battery life.
Key MIC5201 features include current limiting, overtemperature shutdown, and protection against reversed battery.
