DIODES Incorporated Voltage Regulators - Linear AP7343D-09FS4-7B

The AP7343D-09FS4-7B is a low dropout linear voltage regulator designed to provide a stable output voltage with high accuracy and low noise. It operates within a wide input voltage range of 1.7V to 5.25V and can deliver an output current of up to 300mA. The output voltage accuracy is specified at ±1%, and it features a ripple rejection of 75dB at 1kHz, ensuring minimal output noise of 60µVrms across a frequency range of 10Hz to 100kHz. This regulator is particularly suitable for low-power applications such as handheld communication devices, smartphones, and portable media players due to its low quiescent current of 35µA. The device includes an enable pin for power management and is available in compact X2-DFN1010-4 (Type B) and SOT25 packages, facilitating dense PCB layouts. It is also fully RoHS compliant and free from halogens and antimony, making it a suitable choice for environmentally conscious designs.
