AP7335
300mA, Low Quiescent Current, Fast Transient
Low Dropout Linear Regulator
Description
Pin Assignments
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.
