LM2767M5X Equivalent & Substitute Parts

Part Overview

The LM2767M5X is a charge pump switching regulator IC from Texas Instruments designed for positive adjustable voltage regulation. This device operates as a ratiometric regulator with a single adjustable output, delivering up to 15mA across an input voltage range of 1.8V to 5.5V, with output voltage adjustable from 3.6V to 11V. The LM2767M5X is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution of the LM2767M5X is determined by strict equivalence across the following critical parameters:

• Topology: Charge Pump (fixed requirement)
• Output Configuration: Positive (fixed requirement)
• Output Type: Adjustable (fixed requirement)
• Number of Outputs: 1 (fixed requirement)
• Voltage - Input Range: 1.8V to 5.5V (fixed requirement)
• Voltage - Output Range: 3.6V to 11V (fixed requirement)
• Current - Output: 15mA (fixed requirement)
• Frequency - Switching: 11kHz (fixed requirement)
• Package / Case: SC-74A, SOT-753 (fixed requirement)
• Supplier Device Package: SOT-23-5 (fixed requirement)
• Operating Temperature: -40°C ~ 85°C (fixed requirement)

The LM2767M5X/NOPB is a direct manufacturer equivalent that maintains identical electrical and mechanical specifications while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The LM2767M5X/NOPB is the direct equivalent substitute for the obsolete LM2767M5X. Both components share identical electrical specifications and mechanical packaging. The LM2767M5X/NOPB offers two significant advantages: it maintains Last Time Buy status rather than obsolete status, and it achieves ROHS3 compliance compared to the non-compliant status of the original part. For new designs or production continuity, the LM2767M5X/NOPB is the appropriate selection. Both parts are supplied in SOT-23-5 packaging with unlimited moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can the LM2767M5X/NOPB be used as a direct replacement for the LM2767M5X?

A: Yes. The LM2767M5X/NOPB is electrically and mechanically identical to the LM2767M5X across all specified parameters, including input voltage range (1.8V to 5.5V), adjustable output range (3.6V to 11V), output current (15mA), switching frequency (11kHz), operating temperature range (-40°C to 85°C), and package type (SOT-23-5).

Q: What is the difference between the LM2767M5X and LM2767M5X/NOPB?

A: The primary differences are product status and compliance. The LM2767M5X is classified as obsolete, while the LM2767M5X/NOPB is Last Time Buy. Additionally, the LM2767M5X/NOPB is ROHS3 compliant, whereas the LM2767M5X is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any package or pinout differences between these parts?

A: No. Both the LM2767M5X and LM2767M5X/NOPB use the SC-74A, SOT-753 package with SOT-23-5 supplier device packaging. Pinout and mechanical dimensions are identical.

Q: What does Last Time Buy status mean for the LM2767M5X/NOPB?

A: Last Time Buy indicates that the manufacturer will accept orders for a limited time before discontinuing the product. This provides a defined window for procurement before the part becomes unavailable.

Q: Is the LM2767M5X/NOPB suitable for new product designs?

A: The LM2767M5X/NOPB is suitable for new designs within its Last Time Buy window. However, designers should be aware of the limited availability window and plan accordingly for long-term production requirements.
