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