APE8867

Advanced Power Electronics Corp. APE8867 300mA LOW DROPOUT LINEAR REGULATOR FEATURES Application for Extreme Low Output Voltage Guaranteed 300mA Output Current Very Low Quiescent Current at about 40uA ±2% Output Voltage Accuracy Needs Only 1µF Capacitor for Stability Thermal Shutdown / Current Limited Protection Adjusted Mode with 0.8V Reference Voltage Low-ESR Ceramic Capacitor for Output Stability Tiny SOT-23-5L, SOT-23-5LR & SC-70-5L Package Type RoHS Compliant High PSRR DESCRIPTIOON The APE8867 series are low dropout, positive linear regulators with very low quiescent current. The APE8867 can supply 300mA output current with a low dropout voltage & very low output voltage. The APE8867 regulator is able to operate with output capacitors as small as 1µF to 10µF for stability. Other than the current limit protection APE8867 also offers on chip thermal shutdown feature providing protection against overload or any condition when the ambient temperature exceeds the junction temperature. The APE8867 series are available in low-profile, space-saving SOT-23-5L, SOT-23-5LR & SC-70-5L packages.
