AP7315
150mA HIGH PSRR LOW NOISE LDO WITH ENABLE
Description
Pin Assignments
The AP7315 is a 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.
The AP7315 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 AP7315 is well suited for low power handheld communication
equipment.
Pin 1 – VOUT, Pin 2 – GND, Pin 3 – EN, Pin 4 – VIN
The AP7315 is packaged in X2-DFN1010-4, SOT23 and SOT25
packages and allows for smallest footprint and dense PCB layout.
