Renesas Electronics Corporation Voltage Regulators - Linear ISL78302AARLLZ

The ISL78302AARLLZ is a dual low-dropout (LDO) voltage regulator from Quarktwin Technology Ltd., designed to provide two outputs of 2.9V at 300mA each. It operates within an input voltage range of 2.3V to 6.5V and features a low quiescent current of 47¬µA when both outputs are active. The device is characterized by a very high power supply rejection ratio (PSRR) of 90dB at 1kHz and low output noise, typically 30¬µVRMS at 100¬µA load. The ISL78302AARLLZ includes individual power-on reset (POR) functions for each output, with a fixed delay of approximately 2ms for the first output and an externally programmable delay for the second output. It is stable with output capacitance ranging from 1¬µF to 10¬µF and is suitable for automotive applications due to its AEC-Q100 qualification and operating temperature range of -40¬8C to +105¬8C. The device is packaged in a compact 10-lead 3mm x 3mm DFN package, making it suitable for space-constrained designs.
