AP7335 300mA, LOW QUIESCENT CURRENT, FAST TRANSIENT LOW DROPOUT LINEAR REGULATOR Description Pin Assignments The AP7335 is a 300mA, adjustable and fixed output (Top View) (Top View) voltage, low dropout linear regulator. The device included pass element, error amplifier, band-gap, current limit and IN 1 5 OUT IN 1 5 OUT thermal shutdown circuitry. The device is turned on when EN pin is set to logic high level. 2 2 GND GND The characteristics of low dropout voltage and low quiescent EN 3 4 ADJ EN 3 4 NC current make it suitable for low power applications, for example, battery powered devices. The typical quiescent SOT25 SOT25 (Fixed Output) (ADJ Output) current is approximately 35 A. Built-in current-limit and thermal-shutdown functions prevent IC from damage in fault conditions. (Top View) (Top View) EN NC 1 6 This device is available with adjustable output from 0.8V to EN ADJ 1 6 5.0V, and fixed version with 0.8V, 1.0V, 1.2V, 1.5V, 1.8V, NC 2 5 GND 2 5 NC GND 2.0V, 2.5V, 2.7V, 2.8V, 3.0V, 3.3V and 3.9V outputs.
