ISL9000AIRJNZ

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

The ISL9000AIRJNZ is a dual-channel low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics Corporation. It provides two independent positive fixed output channels, typically configured for 1.8V and 2.8V outputs, each capable of sourcing up to 300mA. The device operates within an input voltage range of 2.3V to 6.5V and features a maximum dropout voltage of 0.4V at full load. Key electrical parameters include a quiescent current of 32µA and a supply current of 52µA. It incorporates integrated protection mechanisms such as overcurrent limiting, thermal shutdown, and under-voltage lockout (UVLO), alongside individual Power-On-Reset (POR) functions for each channel.

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 manufacturing date codes relevant to your production timeline. Ensure proper handling procedures are followed due to surface-mount packaging sensitivity. Review official datasheets for latest pin configurations and recommended external component values before integration.

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

Select this component when designing systems requiring dual isolated rails with strict noise constraints. Verify that the required output voltages match available factory-fixed options or consider adjustable variants if flexibility is needed. Ensure the total system current demand does not exceed the 300mA per channel limit. Evaluate thermal dissipation requirements based on the expected input-to-output voltage differential and ambient operating conditions.
