ISL9011AIRMNZ

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

The ISL9011AIRMNZ is a dual low-dropout (LDO) linear voltage regulator manufactured by Intersil, now part of Renesas Electronics. It features two independent output channels housed in a compact 10-lead DFN package measuring 3.0 x 3.0 mm. The device supports an input voltage range from 2.3 V to 6.5 V with fixed output options including 3.0 V and 3.3 V. It delivers a maximum output current of 300 mA per channel with a typical dropout voltage of 250 mV at full load. Key electrical specifications include a noise level of 30 μVRMS (10 Hz to 100 kHz), line regulation of 0.2 %/V, and load regulation of 1 %. Voltage accuracy is maintained within ±1.8 %, and the operating temperature range spans from -40°C to +85°C.

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

Verify component authenticity through authorized distributors due to potential availability constraints. Confirm RoHS compliance and lead-free status prior to integration. Ensure storage conditions adhere to moisture sensitivity level (MSL) 3 guidelines to prevent package damage during soldering. Cross-reference datasheet revisions to confirm pinout and electrical parameter consistency with design specifications.

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

Select this component when dual isolated LDOs are required in a minimal footprint. Compare dropout voltage characteristics against load requirements to ensure regulation stability. Evaluate noise specifications against sensitive downstream components. Consider thermal dissipation capabilities within the DFN package for high-current scenarios. Verify input voltage compatibility with available system power rails.

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

This device belongs to the ISL9011 series of low-power LDO regulators designed for space-constrained applications. The series emphasizes low noise and high PSRR, distinguishing it from standard general-purpose regulators. Intersil's acquisition by Renesas Electronics has integrated this product into a broader portfolio of power management solutions, maintaining its role in portable and industrial electronics.

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

Check for direct pin-compatible alternatives within the ISL9011 family, such as variants with different output voltages or packaging suffixes. Verify that substitute components match the 300 mA output current capability and 30 μVRMS noise specification. Ensure replacement parts maintain the same DFN-10 footprint and thermal characteristics.
