ISL9011AIRNNZ Equivalent & Substitute Parts

Part Overview

The ISL9011AIRNNZ is a linear voltage regulator IC from Renesas Electronics Corporation designed for power management applications. This dual-output positive fixed regulator delivers 150mA and 300mA outputs at 3.3V with a maximum input voltage of 6.5V and dropout voltage of 0.2V at 150mA and 0.325V at 300mA. The device is actively produced and widely used in applications requiring compact, low-noise voltage regulation in surface-mount 10-DFN packages. Alternative parts may be required due to inventory constraints, design revisions, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISL9011AIRNNZ are classified based on electrical and mechanical compatibility within the power management PMIC category. The primary substitution criteria are:

Parametric Equivalents maintain identical or functionally equivalent specifications across all critical parameters: dual positive fixed 3.3V outputs, 150mA and 300mA current ratings, maximum input voltage of 6.5V, dropout voltage performance, quiescent current, protection features (Over Current, Over Temperature, Soft Start, UVLO), operating temperature range (-40°C ~ 85°C), and surface-mount packaging in 10-pin DFN format with exposed pad.

Similar Parts share the same functional output configuration (dual positive fixed 3.3V outputs, 150mA and 300mA current ratings) and operating temperature range but may differ in secondary parameters such as maximum input voltage, dropout voltage characteristics, quiescent current, protection feature set, package variant (SON vs. DFN), or supplier device package designation. These parts are suitable for applications where the primary electrical function is the determining factor and minor parameter variations are acceptable.

Parameter Comparison

Engineering Selection Recommendations

ISL9012IRNNZ is a parametric equivalent to the ISL9011AIRNNZ. Both devices are manufactured by Renesas Electronics Corporation and maintain identical electrical specifications including output voltage, current ratings, dropout voltage, quiescent current, protection features, and operating temperature range. Both are ROHS3 compliant and actively produced. Selection between these two Renesas parts may be based on inventory availability, packaging format preference (both supplied in Tube), or design documentation requirements.

LP5996SD-3333/NOPB is a similar alternative from Texas Instruments suitable for applications where the primary requirement is dual positive fixed 3.3V outputs at 150mA and 300mA with -40°C to 85°C operating temperature. This device differs in maximum input voltage (6V vs. 6.5V), dropout voltage performance (higher at 300mA: 0.55V vs. 0.325V), quiescent current (110 µA vs. 40 µA), and package variant (10-WFDFN vs. 10-VFDFN). The LP5996SD-3333/NOPB is supplied in Tape & Reel format and is ROHS3 compliant. This part is appropriate for designs where the lower maximum input voltage and higher quiescent current are acceptable trade-offs.

All three parts are actively produced and comply with ROHS3 and REACH requirements, supporting long-term design viability.

Frequently Asked Questions (FAQ)

Q: Can ISL9012IRNNZ directly replace ISL9011AIRNNZ?

A: Yes. The ISL9012IRNNZ is a parametric equivalent with identical electrical specifications, output configuration, current ratings, dropout voltage, quiescent current, protection features, and operating temperature range. Both are 10-DFN surface-mount packages with exposed pad. Substitution is direct from an electrical standpoint.

Q: What are the key differences between ISL9011AIRNNZ and LP5996SD-3333/NOPB?

A: The LP5996SD-3333/NOPB differs in three areas: maximum input voltage is 6V (vs. 6.5V), dropout voltage at 300mA is 0.55V (vs. 0.325V), and quiescent current is 110 µA (vs. 40 µA). The package variant is 10-WFDFN (vs. 10-VFDFN). These differences may impact power dissipation and input voltage margin in specific applications.

Q: Are package differences between 10-VFDFN and 10-WFDFN significant?

A: Both are 10-pin DFN packages with 3x3mm footprint and exposed pad for surface mounting. Physical dimensions and PCB layout compatibility are similar. Verify specific package drawings with the respective manufacturers if precise footprint matching is required.

Q: Can I use LP5996SD-3333/NOPB in a design originally specified for ISL9011AIRNNZ?

A: Substitution is possible if the application tolerates the parameter differences: lower maximum input voltage (6V), higher dropout voltage at 300mA (0.55V), and higher quiescent current (110 µA). Verify that input voltage does not exceed 6V and that power dissipation remains within acceptable limits.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging is suitable for manual assembly and small-volume production. Tape & Reel packaging is optimized for automated pick-and-place assembly in high-volume manufacturing. Electrical performance is identical; selection depends on assembly process requirements.

Q: Are all three parts RoHS3 compliant?

A: Yes. ISL9011AIRNNZ, ISL9012IRNNZ, and LP5996SD-3333/NOPB are all ROHS3 compliant and REACH unaffected, supporting compliance with environmental regulations.
