It offers extremely low dropout voltage, very low output noise and can operate from a 2.3V to 5.5V input while delivering up to 150mA. It offers 2% initial accuracy, low ground current (typically 85ìA total), thermal and current limit protection. The MIC5302 can also be put into a zero-off-mode current state, drawing no current when disabled. The MIC5302 is available in the ultra small 4-pin 1.2mm x 1.6mm Thin MLF® package, occupying only 1.92mm2 of PCB area, a 50% reduction in board area compared to SC-70 and 2mm x 2mm MLF® packages. It’s operating junction temperature range is –40°C to +125°C and is available in fixed output voltages in lead-free (RoHS compliant) Thin MLF® package.
