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, 2.7V, 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.
