LM9036MM-3.3 Equivalent & Substitute Parts

Part Overview

The LM9036MM-3.3 is a linear voltage regulator IC from Texas Instruments designed for positive fixed 3.3V output applications with 50mA current capacity in an 8-VSSOP surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The LM9036 series provides regulated power management for low-power applications requiring stable 3.3V output with integrated protection features.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the LM9036MM-3.3 is determined by electrical and mechanical parameter equivalence across the LM9036 product family. All substitute parts maintain identical specifications for output voltage (3.3V fixed), output current (50mA), input voltage rating (40V maximum), voltage dropout characteristics (0.40V @ 50mA), quiescent current (20 µA), PSRR performance (60dB at 120Hz), operating temperature range (-40°C ~ 125°C), and package configuration (8-VSSOP).

The primary differentiators among substitute parts are product status (active versus obsolete), packaging format (bulk versus tape & reel), RoHS compliance status, and automotive qualification level. These factors determine suitability for specific procurement and application requirements without affecting core electrical performance.

Parameter Comparison

Engineering Selection Recommendations

For new designs and ongoing procurement, LM9036MM-3.3/NOPB is the primary direct substitute, offering active product status, ROHS3 compliance, and equivalent electrical performance in tape & reel packaging suitable for automated assembly.

For automotive applications requiring AEC-Q100 qualification, both LM9036QMM-3.3/NOPB and LM9036QMMX-3.3/NOPB provide automotive-grade equivalents with identical electrical specifications and ROHS3 compliance. Selection between these two automotive variants depends on procurement availability and inventory requirements.

The original LM9036MM-3.3 (obsolete status, non-RoHS compliant) should be replaced in active designs. Existing inventory of the obsolete part may be used for legacy system support only.

Frequently Asked Questions (FAQ)

Q: Can LM9036MM-3.3/NOPB directly replace LM9036MM-3.3 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The primary differences are product status (active versus obsolete), RoHS compliance (ROHS3 versus non-compliant), and packaging format (tape & reel versus bulk). Pin configuration, electrical performance, and package dimensions are equivalent.

Q: What is the difference between LM9036QMM-3.3/NOPB and LM9036QMMX-3.3/NOPB?

A: Both parts are automotive-grade (AEC-Q100 qualified) with identical electrical specifications. The difference is the "X" suffix designation in the QMMX variant. Both are suitable for automotive applications requiring AEC-Q100 qualification.

Q: Are the automotive-qualified variants (LM9036QMM-3.3/NOPB and LM9036QMMX-3.3/NOPB) suitable for non-automotive applications?

A: Yes. Automotive-qualified parts meet or exceed standard industrial specifications. They can be used in non-automotive applications where the additional qualification provides design margin and reliability assurance.

Q: Does the tape & reel packaging affect electrical performance compared to bulk packaging?

A: No. Tape & reel packaging is a delivery and handling format only. Electrical performance, specifications, and functionality are identical between bulk and tape & reel variants of the same part number.

Q: Is RoHS3 compliance required for my application?

A: RoHS3 compliance is mandatory for products sold in the European Union and many other regions. For new designs, ROHS3-compliant variants (LM9036MM-3.3/NOPB, LM9036QMM-3.3/NOPB, LM9036QMMX-3.3/NOPB) are recommended. Legacy systems may continue using non-compliant inventory under existing exemptions.

Q: What is the PSRR specification and why does it matter?

A: PSRR (Power Supply Rejection Ratio) of 60dB at 120Hz indicates the regulator's ability to reject power supply noise. All LM9036 variants maintain identical PSRR performance, ensuring consistent noise filtering across all substitute parts.

Q: Can I use these regulators in high-temperature environments?

A: Yes. All variants operate across -40°C to 125°C. Verify that your specific application requirements fall within this range and that thermal management is adequate for the 50mA output current at maximum ambient temperature.
