Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISL9011AIRPLZ is determined by the following critical parameters:

• Dual positive fixed-output voltage regulator configuration
• Output voltage levels: 1.85V and 2.9V (or compatible fixed outputs)
• Dual current ratings: 150mA and 300mA per output
• Surface mount package with 10-pin DFN footprint compatibility
• Maximum input voltage rating of 5.5V or higher
• Integrated protection features: over-current and over-temperature protection
• Operating temperature range support for -40°C to 85°C minimum
• ROHS3 compliance and EAR99 classification

The MIC2211-GOYML-TR from Microchip Technology meets these substitution criteria through functional equivalence in output configuration, voltage ratings, current delivery, package form factor, and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The MIC2211-GOYML-TR qualifies as a functional substitute for the obsolete ISL9011AIRPLZ based on the following engineering criteria:

Product Status & Supply Continuity: The MIC2211-GOYML-TR maintains active production status with documented inventory availability, ensuring long-term supply chain reliability compared to the obsolete ISL9011AIRPLZ.

Regulatory Compliance: Both devices maintain ROHS3 compliance, REACH unaffected status, and EAR99 classification, satisfying regulatory requirements for equivalent component substitution.

Functional Equivalence: Dual positive fixed-output configuration with matching 150mA and 300mA current ratings and compatible 1.8V/2.9V output voltage levels provide direct functional replacement capability.

Package Compatibility: Both devices utilize 10-pin DFN surface mount packages with exposed pad design, supporting direct PCB layout compatibility without redesign requirements.

Design Margin Considerations: The MIC2211-GOYML-TR exhibits higher maximum input voltage tolerance (5.5V vs. 6.5V), extended operating temperature range (-40°C to 125°C vs. -40°C to 85°C), and increased quiescent current (80 µA vs. 40 µA). Applications operating at input voltages exceeding 5.5V or requiring the soft start and UVLO features of the original device require design evaluation.

Frequently Asked Questions (FAQ)

Q: Can the MIC2211-GOYML-TR directly replace the ISL9011AIRPLZ without PCB modifications?

A: Yes, for applications within the MIC2211-GOYML-TR electrical specifications. Both devices share identical 10-pin DFN package geometry and pinout compatibility. However, verify that your application input voltage does not exceed 5.5V and that the absence of soft start and UVLO features does not impact system performance.

Q: What is the output voltage difference between 1.85V and 1.8V?

A: The ISL9011AIRPLZ provides 1.85V fixed output, while the MIC2211-GOYML-TR provides 1.8V fixed output. This 50mV difference may be significant for applications with tight voltage tolerance requirements. Evaluate downstream component specifications to determine compatibility.

Q: Why is the maximum input voltage lower on the MIC2211-GOYML-TR?

A: The MIC2211-GOYML-TR specifies a maximum input voltage of 5.5V compared to 6.5V for the ISL9011AIRPLZ. Applications with input voltages between 5.5V and 6.5V require alternative substitutes or design modification to reduce input voltage.

Q: Does the higher quiescent current of the MIC2211-GOYML-TR affect power consumption?

A: The MIC2211-GOYML-TR draws 80 µA quiescent current versus 40 µA for the ISL9011AIRPLZ, representing a 40 µA increase. For battery-powered or low-power applications, calculate total system power impact to determine acceptability.

Q: Are the protection features identical between these devices?

A: No. The ISL9011AIRPLZ includes soft start and under-voltage lockout (UVLO) protection in addition to over-current and over-temperature protection. The MIC2211-GOYML-TR provides over-current and over-temperature protection only. Applications relying on soft start or UVLO functionality require design evaluation or alternative component selection.

Q: What packaging options are available for the MIC2211-GOYML-TR?

A: The MIC2211-GOYML-TR is available in both 10-VFDFN and 10-MLF® packages. Verify your PCB design specifies the correct package variant to ensure mechanical and electrical compatibility.
