ISL9000IRKKZ

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

The ISL9000IRKKZ is a dual low-dropout linear regulator manufactured by Renesas Electronics Corporation. It provides two independent positive fixed outputs, each capable of sourcing up to 300mA. The device operates with an input voltage range from 2.3V to 6.5V and features a typical dropout voltage of 200mV at full load. Key electrical parameters include a quiescent current of 42µA when both LDOs are active and a power supply rejection ratio of 90dB at 1kHz. The output voltage accuracy is specified at ±1.8% across all operating conditions. It is housed in a compact 10-lead DFN package measuring 3mm x 3mm.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

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

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeits. Confirm RoHS compliance status and check for specific manufacturing date codes relevant to your production timeline. Ensure proper ESD handling procedures are followed during storage and assembly. Validate that the 10-DFN package dimensions match your PCB footprint requirements precisely before finalizing procurement orders.

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

Select this component when dual isolated low-noise supplies are required from a single input rail. It is suitable for designs needing precise voltage regulation with minimal static power consumption. Consider the 300mA output capability against your peak load demands. The wide input voltage range allows flexibility in battery-powered systems. Ensure adequate thermal management is planned given the small package size and potential power dissipation under heavy loads.
