DIODES Incorporated Voltage Regulators - Linear AP7348D-3328RS4-7

The AP7348D-3328RS4-7 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 typically 160µA across all channels, making it suitable for low power handheld communication devices. The regulator is built on a CMOS process and includes essential protection features such as foldback current limiting and over-temperature sensing, which disables all channels during fault conditions. It also offers high power supply rejection ratio (PSRR) of 75dB at 1kHz and low output noise of 60µVrms from 10Hz to 100kHz. The AP7348D-3328RS4-7 is housed in a compact X1-DFN1612-8 (Type B) package, facilitating dense PCB layouts. It is fully RoHS compliant and suitable for automotive applications, provided that specific change control requirements are met.
