MIC5210

The MIC5210 is a dual linear voltage regulator with very low dropout voltage (typically 10mV at light loads and 140mV at 100mA), very low ground current (225µA at 10mA output), and better than 1% initial accuracy. It also features individual logic-compatible enable/shutdown control inputs.

Both regulator outputs can supply up to 150mA at the same time as long as each regulator's maximum junction temperature is not exceeded.

Designed especially for hand-held battery powered devices, the MIC5210 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, over temperature shutdown, and protection against reversed battery.

The MIC5210 is available in 2.7V, 2.8V, 3.0V, 3.3V, 3.6V, 4.0V, and 5.0V fixed voltage configurations. Other voltages are available; contact Microchip for details.
