Description

The AP7312 is 150mA, dual fixed output voltage, low dropout linear regulator. The AP7312 include the pass element, error amplifier, band-gap, current limit and thermal shutdown circuitry which protect the IC from damage in fault conditions. The AP7312 has two enable pins (EN1 and EN2) to independently turn the respective channel on when a logic high level is applied.
