Microchip | MIC5206-3.3YM5-TR

The MIC5206-3.3YM5 TR is an efficient linear voltage regulator with very low dropout voltage (typically 17 mV at light loads and 165 mV at 150 mA), and very low ground current (600 µA at 100 mA output), with better than 1% initial accuracy. It has a logic compatible enable/shutdown control input and an internal under voltage monitor.

Designed especially for hand-held, battery-powered devices, the MIC5206 can be switched by a CMOS or TTL compatible logic signal. When disabled, power consumption drops nearly to zero. Dropout ground current is minimized to prolong battery life.

The MIC5206 is available in several fixed voltages in a tiny SOT-23-5 package. It features a pinout, similar to the LP2980, but has significantly better performance. Fixed and adjustable output voltage versions, featuring the reference bypass option, are available in the 8-lead Micrel Mini 8™ 8-lead MSOP (micro small-outline package).
