The MIC5200 is an efficient linear voltage regulator with very low dropout voltage (typically 17mV at light loads and 200mV at 100mA) and very low ground current (1mA at 100mA output), offering better than 1% initial accuracy with a logic-compatible on/off switching input. Designed especially for handheld battery powered devices, the MIC5200 is switched by a CMOS- or TTL-compatible logic signal. The enable control may be tied directly to VINif unneeded. When disabled, power consumption drops nearly to zero. The ground current of the MIC5200 increases only slightly in dropout, further prolonging battery life. Key MIC5200 features include protection against reversed battery, current limiting, and over-temperature shutdown.The MIC5200 is available in several fixed voltage and accuracy configurations.
