„ General Description
The AP450 series integrates two channel linear
controllers into a single chip, mainly designs for
power-supply regulator. All the functions included
an on-chip 1.25V/0.8V reference output, error
amplifier, UVLO, current limit. During low VCC
situation, the UVLO makes sure that the outputs
are off until the internal circuit is operational
normally.
