Renesas Electronics Corporation Voltage Regulators - Linear ISL9014IRBJZ-T

The ISL9014IRBJZ-T is a dual low-dropout (LDO) voltage regulator from Quarktwin Technology Ltd., capable of sourcing up to 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, ensuring stable output voltage under varying load conditions. This regulator is stable with output capacitance ranging from 1¬µF to 10¬µF and can handle equivalent series resistance (ESR) up to 200mOc. It includes separate enable pins for each LDO, allowing for independent control, and features a soft-start function to limit inrush current during activation. The ISL9014IRBJZ-T also incorporates thermal shutdown and current limit protection to enhance reliability. The output voltage options for this part number include 1.5V for VO1 and 2.8V for VO2, with an operating temperature range of -40¬8C to +85¬8C. The compact 10-lead 3mm x 3mm DFN package makes it suitable for space-constrained applications such as portable devices, PDAs, and medical handhelds.
