AP7346

DUAL HIGH ACCURACY CURRENT LIMIT LDO WITH ENABLE

Description

The AP7346 is a dual high accuracy current limit ,low dropout

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.
