MIC5212
Dual 500mA LDO Regulator
Final
General Description
The MIC5212 is a dual linear voltage regulator with very-low
dropout voltage (typically 10mV at light loads and 350mV at
500mA), very-low ground current (225
μ
A at 10mA output),
and better than 1% initial accuracy.
Both regulator outputs can supply up to 500mA at the same
time as long as each regulator’s maximum junction tempera-
ture is not exceeded.
Key features include current limiting, overtemperature shut-
down, and protection against reversed battery.
The MIC5212 is available in a fixed 3.3V/2.5V output voltage
configuration. Other voltages are available; contact Micrel for
details.
