300mA HIGH PSRR, LOW NOISE, LDO REGULATORS
FEATURES
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
Cellular Phones Notebook Computers PDAs Hand-Held Devices
DESCRIPTION
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.
The APE8833 series are offering several fixed output voltage types and low-profile ,space-saving SOT-23-5L package.
