Renesas Electronics Corporation Voltage Regulators - Linear ISL9014AIRBBZ

The ISL9014AIRBBZ is a dual low-dropout (LDO) voltage regulator from Quarktwin Technology Ltd., capable of sourcing 300mA from each output. It operates within a wide input voltage range of 2.3V to 6.5V and features a low quiescent current of 45¬µA when both LDOs are active. The device is designed for high performance with a high power supply rejection ratio (PSRR) of 70dB at 1kHz and excellent load regulation of less than 1% across the full load current range. The ISL9014AIRBBZ supports output voltage options ranging from 1.5V to 3.3V, with the specific part number providing both outputs at 1.5V. It is stable with output capacitance values between 1¬µF and 10¬µF and has a low dropout voltage of approximately 200mV at 300mA. The device includes features such as separate enable pins for each LDO, soft-start functionality to limit input current surge, and built-in current limit and overheat protection. Operating over a temperature range of -40¬8C to +85¬8C, the ISL9014AIRBBZ is packaged in a compact 10-lead 3mm x 3mm DFN, making it suitable for space-constrained applications such as portable devices, PDAs, and smartphones.
