MIC5207 Datasheet | Micrel Semiconductor

Micrel 180m A Low-Noise LDO Regulator General Description The MIC5207 is an efficient linear voltage regulator with ultralow-noise output, very low dropout voltage (typically 17m V at light loads and 165m V at 150m A), and very low ground current (720µA at 100m A output). The MIC5207 offers better than 3% initial accuracy. Designed especially for hand-held, battery-powered devices, the MIC5207 includes a CMOS or TTL patible enable/ shutdown control input. When 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 overtemperature shutdown. The MIC5207 is available in fixed and adjustable output voltage versions in a small SOT-23-5 package. Contact Micrel for details.
