Contact Sales

Description

The AP7346 is a Dual low dropout regulator with high output voltage accuracy, low RDSON, high PSRR, low output noise and low quiescent current. This regulator is based on a CMOS process. Each of regulators includes a voltage reference, error amplifier, current limit circuit and an enable input to turn on/ off output. With the integrated resistor network fixed output voltage versions can be delivered. With its low power consumption and line and load transient response, the AP7346 is well suited for low power handheld communication equipment. The AP7346 is packaged in X2-DFN1212-6 package and allows for smallest footprint and dense PCB layout.
