AP7340
150mA HIGH PSRR LOW NOISE LDO WITH ENABLE
Description
The AP7340 is 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.
The AP7340 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 response
the AP7340 is well suited for low power handheld communication
equipment.
The AP7340 is packaged in a X2-DFN1010-4 package and allows for
smallest footprint and dense PCB layout.
