LP5912-1.5DRVT Equivalent & Substitute Parts

Part Overview

The LP5912-1.5DRVT is a linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) device. It delivers a fixed 1.5V output at 500mA with integrated control features including Enable, Power Good, and Soft Start functionality. The device is housed in a 6-WSON (2x2) surface mount package with an exposed pad and provides protection against over-temperature, reverse polarity, and short circuit conditions.

The LP5912-1.5DRVT currently holds Last Time Buy status, indicating limited availability. Identifying equivalent substitute parts ensures design continuity and supply chain resilience for applications requiring this specific voltage regulation topology.

Substitute Part Grouping Explanation

Substitute parts for the LP5912-1.5DRVT are identified based on electrical and mechanical parameter equivalence. The following criteria determine substitutability:

Electrical Equivalence Requirements:

• Fixed output voltage of 1.5V
• Output current rating of 500mA
• Maximum input voltage of 6.5V
• Quiescent current of 55 µA
• Maximum supply current of 600 µA
• PSRR specification of 80dB ~ 40dB (100Hz ~ 100kHz)
• Identical control features: Enable, Power Good, Soft Start
• Identical protection features: Over Temperature, Reverse Polarity, Short Circuit
• Operating temperature range of -40°C ~ 125°C

Mechanical Equivalence Requirements:

• 6-WDFN Exposed Pad package (6-WSON 2x2)
• Surface mount mounting type
• RoHS3 compliance
• Moisture Sensitivity Level 1

All identified substitutes meet these criteria. Differences in product status and automotive qualification do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

LP5912-1.5DRVR is the primary substitute for the LP5912-1.5DRVT. This part maintains identical electrical and mechanical specifications while offering Active product status, ensuring continued availability and long-term supply chain support. Selection of this part is appropriate for standard industrial and consumer applications.

LP5912Q1.5DRVRQ1 provides an automotive-qualified alternative with AEC-Q100 certification and Active product status. This part is suitable for automotive applications requiring enhanced reliability qualification. Electrical and mechanical parameters remain equivalent to the main part.

LP5912Q1.5DRVTQ1 offers automotive-grade qualification with AEC-Q100 certification but carries Last Time Buy status. This part is electrically and mechanically equivalent to the main part and suitable for automotive applications where existing inventory or design validation has already been completed.

Selection between these substitutes should be based on application requirements (standard versus automotive), supply availability, and product lifecycle status.

Frequently Asked Questions (FAQ)

Q: Can LP5912-1.5DRVR be used as a direct replacement for LP5912-1.5DRVT?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical output voltage (1.5V), output current (500mA), control features, protection features, and package specifications (6-WDFN Exposed Pad). The primary difference is product status: LP5912-1.5DRVR is Active, while LP5912-1.5DRVT is Last Time Buy.

Q: What is the difference between standard and automotive-qualified versions?

A: The LP5912Q1.5DRVRQ1 and LP5912Q1.5DRVTQ1 variants include AEC-Q100 automotive qualification, indicating enhanced reliability testing and suitability for automotive applications. Electrical and mechanical parameters remain identical to standard versions. Automotive qualification is not required for non-automotive applications.

Q: Are all substitute parts pin-compatible?

A: Yes. All substitute parts use the 6-WDFN Exposed Pad package (6-WSON 2x2) with identical pinout and mechanical dimensions. Direct PCB layout compatibility is maintained across all variants.

Q: Can I use an automotive-qualified part in a non-automotive application?

A: Yes. Automotive-qualified parts meet or exceed standard specifications and can be used in any application. However, this may result in unnecessary cost. Selection should match application requirements.

Q: What should I consider regarding product status when selecting a substitute?

A: Active status parts (LP5912-1.5DRVR and LP5912Q1.5DRVRQ1) offer ongoing availability and long-term supply assurance. Last Time Buy status parts (LP5912-1.5DRVT and LP5912Q1.5DRVTQ1) have limited remaining inventory. For new designs, Active status parts are recommended.

Q: Are there any differences in RoHS or environmental compliance?

A: All parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). Environmental and regulatory compliance is equivalent across all variants.
