Advanced Power Electronics Corp. APE8833 300mA HIGH PSRR, LOW NOISE, LDO REGULATORS FEATURES DESCRIPTION Low, Quiescent Current Guaranteed 300mA Output Current Over-Temperature Protection and Short-Circuit Protection Fixed Mode : 4.75V Ultra Low Supply Shutdown Current Stable with Low Cost Ceramic Capacitors RoHS Compliant & Halogen Free High PSRR APPLICATIONS The APE8833 series are low dropout, positive linear regulators with very low quiescent current. The APE8833 can supply 300mA output current with a low dropout voltage. The APE8833 regulator is able to operate with output capacitors as small as 1µF for stability. Other than the current limit protection APE8833 also offers on chip thermal shutdown feature providing protection against overload or any condition when the ambient temperature exceeds the junction temperature. Cellular Phones Notebook Computers PDAs Hand-Held Devices The APE8833 series are offering several fixed output voltage types and low-profile ,space-saving SOT-23-5L package.

PIN DESCRIPTIONS PIN SYMBOL VIN PIN DESCRIPTION Power is supplied to this device from this pin which is required an input filter capacitor. In general, the input capacitor in the range of 1µF to 10µF is sufficient. GND Common ground pin SHDN Chip Enable (Active High) BP Reference Noise Bypass ( the Bypass Capacitor ≧ 1nF ) The output supplies power to loads. The output capacitor is required to prevent output voltage unstable. The APE8833 is stable with an output VOUT capacitor 1µF or greater. The larger output capacitor will be required for application with large transit load to limit peak voltage transits, besides could reduce output noise, improve stability, PSRR. 3 Advanced Power Electronics Corp.
