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.

物料型号：AP7343

器件简介：AP7343是一款低dropout调节器，具有高输出电压精度、低RDS(ON)、高PSRR、低输出噪声和低静态电流。基于CMOS工艺，包含电压参考、误差放大器、电流限制电路和使能输入，可提供集成电阻网络的固定输出电压版本。

引脚分配：1号引脚为VOUT（电源输出引脚），2号引脚为GND（地），3号引脚为EN（使能引脚，可高电平或低电平驱动，不应悬空），4号引脚为VIN（电源输入引脚），NC表示无连接，EP为暴露的垫，建议在PCB布局中使用大铜面积覆盖此垫以改善散热。

参数特性： - 低输入电压和宽输入电压范围：1.7V至5.25V - 保证输出电流：300mA - 输出电压精度：±1% - 纹波抑制：在1kHz时为75dB - 静态电流低至35µA - 固定输出电压：0.9V至3.6V - 封装信息：X2-DFN1010-4 (Type B) 和 SOT25，无铅、完全符合RoHS标准

功能详解： - 具有使能控制，通过设置EN引脚高电平开启，低电平关闭。 - 短路保护，当VOUT引脚短路至GND时，会触发并限制输出电流至约60mA。 - 应用信息包括智能手机/平板电脑、RF电源、相机、便携式视频、便携式媒体播放器和无线适配器等。

应用信息：适用于无线通信、智能手机/平板电脑、RF电源、相机等。

封装信息：X2-DFN1010-4 (Type B) 和 SOT25封装，具有最小的占用空间和高密度PCB布局。
