MIC5367/8 High Performance 200mA Peak LDO in 1.6mm x 1.6mm Thin MLF General Description Features The MIC5367/8 is an advanced general purpose linear Input voltage range: 2.5V to 5.5V regulator offering high power supply rejection (PSRR) in 200mA peak (150mA continuous) output current an ultra-small 1.6mm x 1.6mm package. The MIC5368 Stable with 1F ceramic output capacitors includes an auto-discharge feature that is activated when Low dropout voltage 180mV 150mA the enable pin is low. The MIC5367/8 is capable of sourcing 200mA peak (150mA continous) output current Excellent Load/Line Transient Response and offers high PSRR making it an ideal solution for any Low quiescent current 29A portable electronic application. High PSRR 65dB Ideal for battery powered applications, the MIC5367/8 Output discharge circuit MIC5368 offers 2% initial accuracy, low dropout voltage (180mV High output accuracy 150mA), and low ground current (typically 29A). The 2% initial accuracy MIC5367/8 can also be put into a zero-off-mode current state, drawing virtually no current when disabled. Tiny 1.6mm x 1.6mm Thin MLF package The MIC5367/8 has an operating junction temperature Thermal shutdown and current limit protection range of 40C to 125C.
