AP7346 Datasheet, PDF (1/14 Pages) Diodes Incorporated – DUAL HIGH ACCURACY CURRENT LIMIT LDO WITH ENABLE

Description
AP7346
DUAL HIGH ACCURACY CURRENT LIMIT LDO WITH ENABLE
Pin Assignments
The AP7346 is a dual high accuracy current limit ,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.
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.
