1 / 16 page AP7343 Document number: DS37952 Rev. 2 - 2 1 of 16 www.diodes.com December 2015 © Diodes Incorporated AP7343 300mA HIGH PSRR LOW NOISE LDO WITH ENABLE Description The AP7343 is a 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 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. With its low power consumption and line and load transient response, the AP7343 is well suited for low power handheld communication equipment. The AP7343 is packaged in an X2-DFN1010-4 package and allows for smallest footprint and dense PCB layout. Features Low VIN and Wide VIN Range: 1.7V to 5.25V Guarantee Output Current: 300mA VOUT Accuracy ±1% Ripple Rejection 75dB at 1kHz Low Output Noise, 60µVrms from 10Hz to 100kHz Quiescent Current as Low as 35µA VOUT Fixed 0.9V to 3.6V Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. “Green” Device (Note 3) Pin Assignments PIN1 – VOUT, PIN2 – GND, PIN3 – EN, PIN4 – VIN Applications Smart Phone/tablet RF Supply Cameras Portable Video Portable Media Player Wireless Adapter Wireless Communication Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant. 2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free,"Green" and Lead-free. 3. Halogen- and Antimony- free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and <1000ppm antimony compounds.
