AP7353 250mA HIGH PSRR LOW NOISE LDO WITH ENABLE Description Pin Assignments The AP7353 is a low dropout regulator with high output voltage (Top View) (Bottom View) accuracy, low R , high PSRR, low output noise and low quiescent DSON : : : 4 OUT 4 OUT : current. This regulator is based on a CMOS process. 1 IN 1 IN The AP7353 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. Top Bump View View With its high PSRR, good line regulation and fast load transient response, the AP7353 is well suited for handheld/wearable communication equipments which require stable voltage sources. : : 2 EN 3 G ND The AP7353 is packaged in X1-WLB0707-4 (Type A1) which allows 3:GND 2: EN for smallest footprint and dense PCB layout.
