LP5912-2.5DRVT Equivalent & Substitute Parts

Part Overview

The LP5912-2.5DRVT is a linear voltage regulator IC from Texas Instruments designed for positive fixed output applications. This device delivers 500mA output current with a fixed 2.5V output and operates across an input voltage range up to 6.5V. The regulator integrates enable, power good, and soft start control features alongside over-temperature, reverse polarity, and short-circuit protection. The part is currently in Last Time Buy status, making identification of equivalent alternatives essential for design continuity and long-term supply chain planning.

Substitute Part Grouping Explanation

Substitution of the LP5912-2.5DRVT is determined by strict equivalence across the following critical parameters:

• Output voltage specification (2.5V fixed)
• Output current capability (500mA minimum)
• Input voltage tolerance (6.5V maximum)
• Dropout voltage performance (0.25V @ 500mA)
• Control feature set (Enable, Power Good, Soft Start)
• Protection mechanisms (Over Temperature, Reverse Polarity, Short Circuit)
• Package form factor (6-WDFN Exposed Pad)
• Operating temperature range (-40°C to 125°C)
• Compliance certifications (ROHS3, MSL 1)

The LP5912-2.5DRVR qualifies as a parametric equivalent based on identical electrical specifications and package configuration. The primary distinction between these parts is packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is available in Cut Tape (CT) and Digi-Reel® format.

Parameter Comparison

Engineering Selection Recommendations

The LP5912-2.5DRVR is a direct parametric equivalent to the LP5912-2.5DRVT. Both parts maintain identical electrical performance, thermal characteristics, and functional capabilities. The LP5912-2.5DRVR holds Active product status, providing extended availability compared to the Last Time Buy designation of the main part.

Selection between these parts should be based on packaging and supply requirements. The LP5912-2.5DRVT is supplied in standard Tape & Reel format suitable for high-volume automated assembly. The LP5912-2.5DRVR is available in Cut Tape and Digi-Reel® formats, accommodating lower-volume or mixed-component procurement scenarios.

Both parts maintain full ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing processes and long-term storage without moisture sensitivity constraints.

Frequently Asked Questions (FAQ)

Q: Are the LP5912-2.5DRVT and LP5912-2.5DRVR electrically identical?

A: Yes. Both parts deliver identical electrical performance, including 2.5V fixed output, 500mA output current, 0.25V dropout voltage at rated current, and all control and protection features. They share the same base product number (LP5912) and are manufactured by Texas Instruments to the same specifications.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. The LP5912-2.5DRVT is supplied in Tape & Reel (TR) format, while the LP5912-2.5DRVR is available in Cut Tape (CT) and Digi-Reel® formats. Both use the same 6-WDFN Exposed Pad package.

Q: Can I substitute the LP5912-2.5DRVR for the LP5912-2.5DRVT in my design?

A: Yes. The LP5912-2.5DRVR is a direct substitute. No circuit modifications or design changes are required. The physical package, pinout, and electrical characteristics are identical.

Q: Why is the LP5912-2.5DRVT marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments is discontinuing this specific packaging variant. The LP5912-2.5DRVR, available in alternative packaging formats, remains in Active status and provides continued supply availability.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical ROHS3 compliance, MSL 1 rating, REACH Unaffected status, and ECCN classification. They are fully interchangeable from a regulatory and compliance perspective.

Q: What packaging format should I select for my application?

A: Select Tape & Reel (TR) format for high-volume automated assembly operations. Select Cut Tape (CT) or Digi-Reel® format for lower-volume applications, prototyping, or mixed-component procurement where standard reel quantities are not required.
