MIC5370/1 High-Performance Dual 150mA LDO 1.6mm x 1.6mm Thin MLF General Description Features The MIC5370/1 is an advanced dual LDO ideal for 2.5V to 5.5V input voltage range powering general purpose portable devices. The Two 150mA output current LDOs MIC5370/1 provides two independently-controlled, high- High output accuracy performance 150mA LDOs in a tiny 1.6mm x 1.6mm Thin 2% initial accuracy MLF package. Low quiescent current 32A per LDO Ideal for battery-powered applications, the MIC5370/1 Stable with 1F ceramic output capacitors offers 2% initial accuracy, low dropout voltage (155mV 150mA) and low ground current (typically 32A per LDO). Independent enable pins The MIC5370/1 can also be put into a zero-off-mode Low dropout voltage 155mV at 150mA current state, drawing virtually no current when disabled. Thermal-shutdown protection When the MIC5371 is disabled an internal resistive load is Current-limit protection automatically applied to the output to discharge the output Output discharge circuit MIC5371 capacitor. This LDO offers fast transient response and high PSRR while consuming a minimum operating current. 6-pin 1.6mm x 1.6mm Thin MLF package The MIC5370/1 is available in fixed output voltages in a lead-free (RoHS-compliant) 6-pin 1.6mm x 1.6mm Thin Applications MLF package.
