- 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.
