TPS76901DBVT Equivalent & Substitute Parts

Part Overview

The TPS76901DBVT is a linear voltage regulator IC from Texas Instruments designed for positive adjustable output applications. This device delivers 100mA output current in a compact SOT-23-5 surface mount package. The part is currently in Last Time Buy status, making identification of equivalent and substitute parts essential for design continuity and procurement planning. Substitute parts maintain identical electrical specifications and package compatibility while offering different product status or qualification levels.

Substitute Part Grouping Explanation

Substitution of the TPS76901DBVT is determined by strict equivalence across the following critical parameters:

• Output configuration (Positive)
• Output type (Adjustable)
• Voltage specifications (Input Max: 10V, Output Min: 1.2V, Output Max: 5.5V)
• Current rating (100mA output, 28 µA quiescent)
• Performance characteristics (PSRR: 60dB at 1kHz)
• Protection features (Over Current, Over Temperature, Reverse Polarity)
• Operating temperature range (-40°C ~ 125°C)
• Package type (SOT-23-5)
• Compliance standards (ROHS3, REACH Unaffected)

Two substitute parts meet these criteria: TPS76901DBVR and TPS76901QDBVRG4Q1. Both maintain identical electrical and mechanical specifications. The primary differences are product status and, in the case of TPS76901QDBVRG4Q1, automotive qualification.

Engineering Selection Recommendations

For applications currently using TPS76901DBVT, the TPS76901DBVR is the direct functional equivalent with active product status and significantly higher inventory availability (91574 units). This part is suitable for standard industrial and commercial applications requiring a positive adjustable linear regulator with 100mA output capacity.

The TPS76901QDBVRG4Q1 is the appropriate selection for automotive applications. This variant carries AEC-Q100 qualification and automotive-grade designation while maintaining identical electrical specifications. Use this part when designs require automotive compliance or are deployed in automotive environments.

Both substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance profile of the original TPS76901DBVT.

Frequently Asked Questions (FAQ)

Q: Can TPS76901DBVR be used as a direct replacement for TPS76901DBVT?
