AP7343-105FS4-7B

AP7343 300mA HIGH PSRR LOW NOISE LDO WITH ENABLE Description Pin Assignments The AP7343 is a low dropout regulator with high output voltage accuracy, low RDS(ON), high PSRR, low output noise, and low (Top View) (Bottom View) quiescent current. This regulator is based on a CMOS process. The AP7343 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. EP With its low power consumption and line and load transient response, the AP7343 is well suited for low-power handheld communication equipment. X2-DFN1010-4 (Type B) PIN1 – VOUT, PIN2 – GND, PIN3 – EN, PIN4 – VIN The AP7343 is packaged in the X2-DFN1010-4 (Type B) and SOT25 packages, allowing for the smallest footprint and a dense PCB layout.
