    AP7344
    DUAL 300mA HIGH PSRR LOW NOISE LDO WITH ENABLE Description
    The AP7344 is a Dual low dropout regulator with high output voltage accuracy, low RDSON, high PSRR, low output noise and low quiescent Pin Assignments VIN1 VOUT1 current. This regulator is based on a CMOS process. Each of regulators includes a voltage reference, error amplifier, current limit circuit and an enable input to turn on/ off output. With the integrated resistor network fixed output voltage versions can be delivered. NEW PRODUCT With its low power consumption and line and load transient response, the AP7344 is well suited for low power handheld communication equipment. The AP7344 is packaged in X2-DFN1612-8 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: 60Vrms from 10Hz to 100kHz Quiescent Current as Low as 50A VOUT Fixed 1.2V to 3.6V Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free, Green Device (Note 3) Applications Smart Phone/PAD 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. Typical Applications Circuit

    Pin Number GND VOUT1 VOUT2 Pin Name 1, 4 2 3 Ground Channel 1 Output Voltage pin Channel 2 Output Voltage pin Chanel 2 Enable pin. This pin should be driven either high or low and must not be floating. Driving this pin high enables channel 2 output, while pulling it low puts Chanel 2 regulator into shutdown mode. Input Voltage pin Input Voltage pin Chanel 1 Enable pin. This pin should be driven either high or low and must not be floating. Driving this pin high enables channel 1 output, while pulling it low puts Chanel 1 regulator into shutdown mode. In PCB layout, prefer to use large copper area to cover this pad for better thermal dissipation, then ...
