MIC5207-5.0YM5-TR

The MIC5207 is an efficient linear voltage regulator with ultra-low-noise output, very low dropout voltage (typically 17 mV at light loads and 165 mV at 150 mA), and very low ground current (720 μA at 100 mA output). The MIC5207 offers better than 3% initial accuracy. Designed especially for hand-held, battery-powered devices, the MIC5207 includes a CMOS or TTL compatible enable/shutdown control input. When in shutdown, power consumption drops nearly to zero. Key MIC5207 features include a reference bypass pin to improve its already low-noise performance, reversed-battery protection, current limiting, and over temperature shutdown. The MIC5207 is available in fixed and adjustable output voltage versions in a small SOT-23-5 package.
