Description

The AP7332 is 300mA, dual fixed output voltage, low dropout linear regulator. The AP7332 includes the pass element, error amplifier, band-gap, current limit and thermal shutdown circuitry which protect the IC from damage in fault conditions. The AP7332 has two enable pins (EN1 and EN2) to independently turn the respective channel on when a logic high level is applied. The characteristics of low dropout voltage and low quiescent current make it suitable for low power applications. The typical quiescent current is approximately 60μA. This device is available with fixed output options of 1.0V/1.0V, 1.0V/3.3V, 1.2V/1.8V, 1.2V/3.3V, 1.5V/2.8V, 1.5V/3.0V, 1.5V/3.3V, 1.8V/2.8V, 1.8V/3.0V, 1.8V/3.3V, 2.5V/3.0V, 2.8V/3.3V and 3.3V/3.3V. For other output options please contact our local sales representative directly or through our distributor located in your area. The AP7332 is available in SOT26 and DFN2018-6 packages.
