ISL9000AIRKCZ

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The ISL9000AIRKCZ is a dual low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics, formerly Intersil. It integrates two independent 300mA LDOs in a compact 10-lead DFN package measuring 3x3 mm. The device operates with an input voltage range of 2.3V to 6.5V and provides fixed output voltages of 1.8V and 2.85V. It features extremely low quiescent current of 32µA, high power supply rejection ratio (PSRR) of 90dB at 1kHz, and excellent load regulation of less than 0.1%. The unit includes individual Power-On-Reset functions and protection against overcurrent and thermal overload.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific manufacturer status, as this component may be discontinued or subject to product change notices. Confirm that the 10-DFN package dimensions and pinout match your PCB footprint requirements. Ensure compatibility with RoHS3 compliance standards if required by your manufacturing process. Check for any updated datasheet revisions that might affect electrical characteristics or ordering information before finalizing procurement plans.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when designing circuits that require two distinct fixed voltage outputs from a single regulator IC. It is suitable for applications demanding low standby current to extend battery life. Consider its performance if your design requires high PSRR to suppress input noise. Verify that the required output currents do not exceed 300mA per channel and that the input voltage remains within the specified operational range.
