Description

The AP7343Q is a low dropout regulator with high output voltage accuracy, low RDS(ON), high PSRR, low output noise and low quiescent current. This regulator is based on a CMOS process.


The AP7343Q includes a voltage reference, error amplifier, current limit circuit, and an enable input to turn it on and off. With the integrated resistor network fixed output voltage versions can be delivered.


With its low power consumption and, line and load transient responses the AP7343Q is well suited for noise sensitive automotive applications.
The AP7343Q is packaged in SOT25 packages, which allows for the smallest footprint and dense PCB layout.
