Description

The APE8805 series are low dropout, positive

linear regulators with very low quiescent current.

The APE8805 can supply 600mA output current

with a low dropout voltage at about 600mV.

The APE8805 regulator is able to operate with

output capacitors as small as 1µF for stability.

Other than the current limit protection APE8805

also offers on chip thermal shutdown feature

providing protection against overload or any

condition when the ambient temperature exceeds

the junction temperature.

The APE8805 series are available in fixed output

voltage ranging from 1.8 volt , 2.5 volt and 3.3 volt.

The APE8805 series are available in space-saving

SOT-23, SOT-89, and SOT-223 packages.
