TPS720105DRVR Equivalent & Substitute Parts

Part Overview

The TPS720105DRVR is a linear voltage regulator IC from Texas Instruments designed for power management applications. It delivers a fixed positive output of 1.05V at 350mA with a maximum dropout voltage of 0.2V. The device is housed in a 6-WSON (2x2) surface mount package and includes integrated protection features for over-current, over-temperature, and under-voltage lockout conditions. As an active product with full RoHS3 compliance and unlimited moisture sensitivity rating, the TPS720105DRVR remains in production. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required for design flexibility, inventory management, or supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS720105DRVR are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

• Fixed output voltage of 1.05V
• Output current rating of 350mA
• Maximum input voltage of 4.5V
• Dropout voltage specification of 0.2V @ 350mA
• Quiescent current of 38 µA
• PSRR performance of 85dB ~ 50dB (10Hz ~ 1MHz)
• Operating temperature range of -40°C ~ 125°C
• 6-WSON (2x2) surface mount package
• Identical protection features (Over Current, Over Temperature, UVLO)
• Enable control feature
• Positive fixed output configuration with single regulator

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both the TPS720105DRVR and TPS720105DRVT are active products from Texas Instruments with identical electrical specifications and mechanical packaging. Selection between these parts may be based on:

• Packaging format preference (Tape & Reel for both)
• Inventory availability and lead time
• Supply chain logistics and regional sourcing
• Design documentation and qualification history

Both parts maintain full RoHS3 compliance and REACH unaffected status, ensuring regulatory compatibility for industrial and commercial applications. The unlimited moisture sensitivity rating (MSL 1) permits storage without time-based constraints.

Frequently Asked Questions (FAQ)

Q: Can TPS720105DRVT be used as a direct replacement for TPS720105DRVR?

A: Yes. Both parts are parametric equivalents with identical electrical performance, output voltage, current rating, dropout voltage, protection features, and 6-WSON (2x2) package specifications. They are interchangeable at the circuit level.

Q: Are there any differences in the package or mounting between these parts?

A: No. Both parts use the 6-WDFN Exposed Pad package with 6-WSON (2x2) supplier device package designation. Surface mount assembly procedures are identical.

Q: Do both parts meet the same compliance and regulatory requirements?

A: Yes. Both the TPS720105DRVR and TPS720105DRVT are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings. They meet identical regulatory standards.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is based on fixed output voltage (1.05V), output current (350mA), input voltage maximum (4.5V), dropout voltage (0.2V @ 350mA), quiescent current (38 µA), PSRR performance (85dB ~ 50dB), operating temperature range (-40°C ~ 125°C), and protection features (Over Current, Over Temperature, UVLO).

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts share identical thermal specifications, quiescent current, supply current limits, and PSRR characteristics across the 10Hz to 1MHz frequency range.
