1 / 9 page April 2003 1 MIC5212 MIC5212 Micrel 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 µA 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.
