Microchip Technology MIC5208-3.3BMM

Description
The MIC5208 is a dual linear voltage regulator with low dropout voltage (20mV at light loads, 250mV at 50mA), low ground current (225μA at 10mA output), and initial accuracy better than 3%. It features individual logic-compatible enable/shutdown control inputs. Designed for handheld battery-powered devices, the MIC5208 can be switched by a CMOS or TTL compatible logic signal or connected to the supply input for 3-terminal operation. When disabled, power consumption drops to nearly zero. Dropout ground current is minimized to prolong battery life. Key features include current limiting, overtemperature shut-down, and protection against reversed battery.
