Description

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

Both regulator outputs of MIC5210 can supply up to 150mA at the same time as long as each regulator's maximum junction tempera-ture 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 con-sumption drops nearly to zero. Dropout ground current is minimized to prolong battery life.

Key features of MIC5210 include current limiting, overtemperature shut-down, 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 Micrel for details.
