1. Description

The MIC5205-5.0YM5-TR is an efficient linear voltage regulator with ultra low-noise output, very low dropout voltage, and very low ground current (600 µA at 100 mA output). The MIC5205-5.0YM5-TR offers better than 1% initial accuracy. Designed especially for hand-held, battery-powered devices, the MIC5205-5.0YM5-TR includes a CMOS or TTL compatible enable/shutdown control input. When shut down, power consumption drops nearly to zero. Regulator ground current increases only slightly in dropout, further prolonging battery life. Key MIC5205-5.0YM5-TR features include a reference bypass pin to improve its already excellent low-noise performance, reversed-battery protection, current limiting, and overtemperature shutdown. The MIC5205-5.0YM5-TR is available in fixed and adjustable output voltage versions in a small SOT-23-5 package.
