Microchip | MIC5202-5.0YM-TR

The MIC5202-5.0YM TR is a family of dual linear voltage regulators with very low dropout voltage (typically 17 mV at light loads and 210 mV at 100 mA), and very low ground current (1 mA at 100 mA output–each section), offering better than 1% initial accuracy with a logic compatible ON/OFF switching input. Designed especially for hand-held battery powered devices.

The MIC5202 is switched by a CMOS or TTL compatible logic signal. This ENABLE control may be tied directly to V IN if unneeded. When disabled, power consumption drops nearly to zero. The ground current of the MIC5202 increases only slightly in dropout, further prolonging battery life. Key MIC5202 features include protection against reversed battery, current limiting, and over-temperature shutdown. The MIC5202 is available in several fixed voltages.
