AP7335A-50
300mA, LOW QUIESCENT CURRENT,
FAST TRANSIENT LOW DROPOUT LINEAR REGULATOR
Description
Pin Assignments
The AP7335A-50 is a 300mA, 5.0V fixed output voltage, low-dropout
linear regulator with ±1% output voltage accuracy. The device
includes 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 35μA. Built-in,
current-limit and thermal-shutdown functions prevent IC from damage
in fault conditions.
This device is only available as a 5.0V fixed version. Please contact
your local sales office for any other voltage options.
The AP7335A-50 is packaged in SOT25 and U-DFN2020-6.
