The MIC5208-3.3BMM-TR is a dual linear voltage regulator with very low dropout voltage (typically 20mV at light loads and 250mV at 50mA), very low ground current (225µA at 10mA output), and better than 3% initial accuracy. It also features individual logic-compatible enable/shutdown control inputs.
Designed especially for hand-held battery powered devices, the MIC5208-3.3BMM-TR can be switched by a CMOS or TTL compatible logic signal, or the enable pin can be connected to the supply input for 3-terminal operation. When disabled, power consumption drops nearly to zero. Dropout ground current is minimized to prolong battery life.
Key features include current limiting, overtemperature shutdown, and protection against reversed battery.
The MIC5208-3.3BMM-TR is available in 3.0V, 3.3V, 3.6V, 4.0V, and 5.0V fixed voltage configurations.
