ISL9000IRNNZ-T

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

The ISL9000IRNNZ-T is a dual-output low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics Corporation. It integrates two independent 300mA LDOs within a compact 10-lead DFN package measuring 3mm x 3mm. The device provides fixed 3.3V outputs with an input voltage range of 2.3V to 6.5V. Key electrical characteristics include a maximum dropout voltage of 0.325V at full load, a typical quiescent current of 42µA, and high power supply rejection ratio performance.

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

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific environmental certifications required by your region. Ensure the ordering suffix matches the exact reel or cut-tape packaging configuration needed for your assembly process. Review the latest product change notification for any updates to pinout or specifications.

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

Select this component when a dual 3.3V output is required from a single input source between 2.3V and 6.5V. It is suitable for designs prioritizing small footprint due to the 3x3mm DFN package. Consider the 0.325V dropout voltage at 300mA load when calculating minimum input voltage requirements. Verify that the 42µA quiescent current meets the standby power constraints of the application.
