LM9036MM-5.0 Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The LM9036MM-5.0 is a linear voltage regulator IC from Texas Instruments designed for positive fixed 5V output applications with 50mA current capacity in an 8-VSSOP surface mount package. This part is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The LM9036 series provides regulated 5V output with integrated protection features including over-temperature, reverse polarity, and short circuit protection, suitable for low-power applications requiring stable voltage regulation.

Substitute Part Grouping Explanation

Substitution of the LM9036MM-5.0 is determined by strict equivalence across the following critical parameters:

Output voltage: 5V fixed
Maximum output current: 50mA
Maximum input voltage: 40V
Voltage dropout: 0.40V @ 50mA
Package type: 8-VSSOP
Mounting configuration: Surface mount
Protection features: Over temperature, reverse polarity, short circuit

Engineering Selection Recommendations

For new designs and production applications, LM9036MM-5.0/NOPB is the primary substitute for the obsolete LM9036MM-5.0. Both parts are electrically and mechanically identical with identical electrical performance specifications. The /NOPB variant achieves ROHS3 compliance and is available in active production status with higher inventory availability (3094 pcs vs. 2000 pcs).

LM9036QMM-5.0/NOPB and LM9036QMMX-5.0/NOPB are suitable substitutes for applications requiring automotive-grade components with AEC-Q100 qualification. These variants maintain all electrical parameters while providing automotive qualification and ROHS3 compliance. The packaging format differs (Tape & Reel vs. Cut Tape & Digi-Reel), which may affect procurement and assembly processes depending on production volume and equipment configuration.

Selection between substitute options should be based on compliance requirements (RoHS status), automotive qualification needs, and packaging format compatibility with existing assembly processes.

Frequently Asked Questions (FAQ)

Q: Can LM9036MM-5.0/NOPB be used as a direct replacement for LM9036MM-5.0?

A: Yes. Both parts are electrically and mechanically identical. The /NOPB variant is the active production equivalent with ROHS3 compliance and higher inventory availability.

Q: What is the difference between LM9036QMM-5.0/NOPB and LM9036QMMX-5.0/NOPB?

A: Both parts are electrically identical with AEC-Q100 automotive qualification. The primary difference is packaging format: LM9036QMM-5.0/NOPB is supplied in standard Tape & Reel, while LM9036QMMX-5.0/NOPB is also supplied in Tape & Reel. Both are suitable for automotive applications.

Q: Are the automotive-grade variants (LM9036QMM-5.0/NOPB and LM9036QMMX-5.0/NOPB) required for non-automotive applications?

A: No. For non-automotive applications, LM9036MM-5.0/NOPB provides identical electrical performance without automotive qualification. Automotive-grade variants are necessary only when AEC-Q100 certification is a design requirement.

Q: Does the packaging format affect electrical performance?

A: No. Packaging format (Cut Tape & Digi-Reel vs. Tape & Reel) affects procurement and assembly logistics only. Electrical specifications and performance remain identical across all variants.

Q: What is the significance of the /NOPB designation?

A: The /NOPB suffix indicates lead-free (no-lead) and RoHS-compliant packaging, meeting ROHS3 standards for environmental compliance.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All substitute parts use identical 8-VSSOP package dimensions (0.118", 3.00mm width) and pin configurations, enabling direct PCB layout compatibility without design modifications.
