AP7344  
DUAL 300mA HIGH PSRR LOW NOISE LDO WITH ENABLE  
Description  
Pin Assignments  
The AP7344 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 AP7344 is well suited for low power handheld communication  
equipment.  
The AP7344 is packaged in X2-DFN1612-8 package and allows for  
smallest footprint and dense PCB layout.
