Description

The AP7335 is a 300mA, adjustable and fixed output voltage, low dropout linear regulator. The device included pass element, error amplifier, band-gap, current limit and thermal shutdown circuitry. The device is turned on when EN pin is set to logic high level. The characteristics of low dropout voltage and low quiescent current make it suitable for low power applications, for example, battery powered devices. The typical quiescent current is approximately 35μA. Built-in current-limit and thermal-shutdown functions prevent IC from damage in fault conditions. This device is available with adjustable output from 0.8V to 5.0V, and fixed version with 0.8V, 1.0V, 1.2V, 1.5V, 1.8V, 2.0V, 2.5V, 2.8V, 3.0V, 3.3V and 3.9V outputs. Please contact your local sales office for any other voltage options. The AP7335 is available in SOT25 and DFN2020-6 packages.
