The MIC5201-3.0YM 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 MIC5201-3.0YM can be switched by a CMOS- or TTL-compatible 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 MIC5201-3.0YM increases only slightly in dropout, further prolonging battery life. Key MIC5201-3.0YM features include current limiting, over-temperature shutdown, and protection against reversed battery.
The MIC5201-3.0YM is available in several fixed voltages and accuracy configurations. It features the same pinout as the LT1121 with better performance.
