NOT RECOMMENDED FOR NEW DESIGN USE AP7344, AP7345D AP7332 DUAL 300mA LOW QUIESCENT CURRENT FAST TRANSIENT LOW DROPOUT LINEAR REGULATOR Description Pin Assignments The AP7332 is 300mA, dual fixed output voltage, low dropout linear regulator. The AP7332 includes the pass element, (Top View) error amplifier, band-gap, current limit and thermal shutdown circuitry which protect the IC from damage in fault conditions. 1 6 OUT2 OUT1 The AP7332 has two enable pins (EN1 and EN2) to independently turn the respective channel on when a logic 2 5 GND IN high level is applied. The characteristics of low dropout voltage and low quiescent EN2 3 4 EN1 current make it suitable for low power applications. The typical quiescent current is approximately 60A. This device is available with fixed output options of SOT26 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/2.7V, 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 (Top View) representative directly or through our distributor located in your area.
