DIODES Incorporated Voltage Regulators - Linear AP7345D-2818RH4-7

The AP7345D-2818RH4-7 is a dual low dropout (LDO) voltage regulator from Quarktwin Technology Ltd. designed to provide high output voltage accuracy and low noise. It supports an input voltage range of 1.7V to 5.25V and can deliver a guaranteed output current of 300mA per channel. The output voltage accuracy is ±1%, with a ripple rejection of 75dB at 1kHz and low output noise measured at 60µVrms from 10Hz to 100kHz. The device features a low quiescent current of 50µA, making it suitable for low power applications such as handheld communication devices, smartphones, and portable media players. The AP7345D-2818RH4-7 is packaged in a compact X2-DFN1612-8 format, allowing for efficient PCB layout. It is fully RoHS compliant and free from halogens and antimony, aligning with environmental standards. This regulator includes integrated features such as voltage reference, error amplifier, and current limit circuit, along with enable inputs for each channel to control the output.
