ISL9000IRCJZ

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

The ISL9000IRCJZ is a dual low-dropout (LDO) linear voltage regulator manufactured by Intersil, now part of Renesas Electronics. It operates within an input voltage range of 2.3 V to 6.5 V and provides two fixed output voltages: 1.8 V and 2.8 V. Each channel delivers up to 300 mA of output current. The device features a typical dropout voltage of 200 mV at full load and maintains a quiescent current of approximately 42 µA with both LDOs active. It offers excellent load regulation of less than 0.1% and voltage accuracy of ±1.8%. The IC is housed in a compact 10-lead DFN package measuring 3 mm x 3 mm.

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

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability issues. Confirm RoHS compliance status and specific manufacturing date codes against project requirements. Check for end-of-life notifications or obsolescence notices that may impact long-term supply continuity. Ensure proper handling procedures are followed during storage and assembly to maintain device integrity.

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

Select this component when dual isolated outputs are required from a single input rail. Consider the 300mA per channel limit for load requirements. Evaluate the need for integrated reset functions versus external logic. Assess thermal performance based on expected power dissipation in the DFN-10 package. Compare quiescent current specifications against battery life targets for portable designs.
