MIC5207 Micrel MIC5207 180mA Low-Noise LDO Regulator General Description Features The MIC5207 is an efficient linear voltage regulator with ultra- � Ultra-low-noise output low-noise output, very low dropout voltage (typically 17mV at � High output voltage accuracy light loads and 165mV at 150mA), and very low ground � Guaranteed 180mA output current (720�A at 100mA output). The MIC5207 offers better � Low quiescent current than 3% initial accuracy. � Low dropout voltage � Extremely tight load and line regulation Designed especially for hand-held, battery-powered devices, � Very low temperature coefficient the MIC5207 includes a CMOS or TTL compatible enable/ � Current and thermal limiting shutdown control input. When shutdown, power consump- � Reverse-battery protection tio
