DIODES Incorporated Voltage Regulators - Linear AP7343D-20FS4-7B

The AP7343D-20FS4-7B is a low dropout linear voltage regulator designed for high output voltage accuracy and low power consumption. It operates within a wide input voltage range of 1.7V to 5.25V and can deliver a guaranteed output current of 300mA. The output voltage accuracy is ±1%, and it features a ripple rejection of 75dB at 1kHz, along with low output noise measured at 60µVrms from 10Hz to 100kHz. The quiescent current is as low as 35µA, making it suitable for low-power applications. This regulator includes an enable pin for on/off control and integrates a voltage reference, error amplifier, and current limit circuit. It is available in compact X2-DFN1010-4 (Type B) and SOT25 packages, facilitating dense PCB layouts. The device is fully RoHS compliant and is suitable for various applications, including smartphones, tablets, and wireless communication devices.
