DIODES Incorporated Voltage Regulators - Linear AP7348D-3028RS4-7

The AP7348D-3028RS4-7 is a four-channel low dropout linear voltage regulator designed for applications requiring high output voltage accuracy and low noise. Each channel can deliver up to 300mA of output current, with a fixed output voltage range from 1.2V to 3.6V and an accuracy of ±1%. The device features a low quiescent current of approximately 160µA for all channels combined, making it suitable for low power applications such as handheld communication devices. The regulator boasts a high power supply rejection ratio (PSRR) of 75dB at 1kHz and low output noise of 60µVrms across a frequency range of 10Hz to 100kHz. It includes built-in protections such as foldback current limiting and over-temperature sensing, which disables all channels during fault conditions. The AP7348D-3028RS4-7 is housed in a compact X1-DFN1612-8 (Type B) package, facilitating dense PCB layouts. It is also fully RoHS compliant and suitable for automotive applications, provided that specific change control requirements are met.
