DESCRIPTION
The APE8839A is an efficient, precise dual-channel CMOS
LDO regulator optimized for ultra-low-quiescent applications.
Regulators output1 and output2 are capable of sourcing 600mA
of output current. The regulators are stable with output
capacitors as low as 1μF, including current limit, thermal
shutdown protection, fast transient response, low dropout
voltage, high output accuracy, current limiting protection, and
high ripple rejection ratio. The APE8839A contains internal pull
high enable function that allows the output of each regulator to
be turned off independently. The APE8839A regulators are
available in used SO-8 with Exposed Pad package.
