MIC5207 180mA Low-Noise LDO Regulator Features General Description Output voltage range: 1.8V 15V The MIC5207 is an efficient linear voltage regulator with Ultra-low-noise output ultra-low-noise output, very low dropout voltage (typically 17mV at light loads and 165mV at 150mA), and very low High output voltage accuracy ground current (720A at 100mA output). The MIC5207 Guaranteed 180mA output offers better than 3% initial accuracy. Low quiescent current Designed especially for hand-held, battery-powered Low dropout voltage devices, the MIC5207 includes a CMOS or TTL compatible Extremely tight load and line regulation enable/shutdown control input. When in shutdown, power Very low temperature coefficient consumption drops nearly to zero. Current and thermal limiting Key MIC5207 features include a reference bypass pin to Reversed-battery protection improve its already low-noise performance, reversed- Zero off-mode current battery protection, current limiting, and over temperature shutdown. Logic-controlled electronic enable The MIC5207 is available in fixed and adjustable output Applications voltage versions in a small SOT-23-5 package. Contact Cellular telephones Micrel for details.
