ISL9011AIRKCZ

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

The ISL9011AIRKCZ is a dual low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics. It operates within an input voltage range of 2.3 V to 6.5 V and provides fixed output voltages of 1.8 V and 2.85 V. The device delivers a maximum output current of 150 mA per channel. It features a typical quiescent current of 45 µA with both channels enabled. The regulator includes an enable/shutdown control pin and is housed in a 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 counterfeit risks. Confirm the specific suffix indicates the tape-and-reel packaging variant if required for automated assembly processes. Check for end-of-life status or obsolescence notices before finalizing procurement plans to ensure long-term supply chain stability.

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

Select this component when designing circuits that require two distinct fixed voltage levels from a single regulator unit. Ensure the load current requirements do not exceed the 150 mA limit per channel. Verify that the application environment remains within the specified -40°C to +85°C operating temperature range. Consider the physical footprint constraints of the 3x3 mm DFN package during PCB layout planning.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the ISL9011A series of dual LDO regulators designed for low-power, space-constrained applications. It replaces older Intersil designs under the Renesas Electronics portfolio following corporate acquisitions. The series emphasizes low standby current and high PSRR, making it suitable for noise-sensitive analog and RF sections in mixed-signal systems.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Consult official Renesas documentation for qualified alternative part numbers within the same family. Verify pin compatibility and electrical specifications before substituting with other dual LDO models. Cross-reference datasheets to ensure equivalent dropout voltage and thermal performance characteristics match the original design requirements.
