TPS77001DBVT Equivalent & Substitute Parts

Part Overview

The TPS77001DBVT is a linear voltage regulator IC from Texas Instruments designed for positive adjustable output applications. It delivers 50mA output current in a compact SOT-23-5 surface mount package. The device features adjustable output voltage ranging from 1.2V to 5.5V with integrated protection against overcurrent, overtemperature, and reverse polarity conditions.

The TPS77001DBVT carries a Last Time Buy product status, indicating this part number is being phased out. Identifying equivalent substitute parts ensures design continuity and supply chain reliability for new production runs and long-term component availability.

Parameter Comparison

Engineering Selection Recommendations

The TPS77001DBVR is a parametric equivalent to the TPS77001DBVT. Both parts share identical electrical specifications, mechanical packaging, and compliance certifications. The primary distinction is product lifecycle status: the TPS77001DBVT is designated Last Time Buy, while the TPS77001DBVR maintains Active product status.

For new designs and ongoing production requirements, the TPS77001DBVR is the appropriate selection due to its active availability and extended supply chain support. The TPS77001DBVR is available in both Cut Tape and Digi-Reel packaging options, providing flexibility for different procurement and assembly workflows.

Both parts satisfy ROHS3 compliance and REACH unaffected requirements, ensuring regulatory alignment for current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can TPS77001DBVR directly replace TPS77001DBVT in existing designs?

A: Yes. The TPS77001DBVR is a direct parametric equivalent. All electrical specifications, output voltage range (1.2V to 5.5V), output current (50mA), protection features, and operating temperature range are identical. The SOT-23-5 package dimensions and pinout are unchanged, enabling direct PCB-level substitution without circuit modification.

Q: What is the difference between Cut Tape and Digi-Reel packaging?

A: Cut Tape packaging supplies components in individual strips, suitable for lower-volume orders and manual assembly. Digi-Reel packaging provides components on continuous reels, optimized for automated pick-and-place assembly in high-volume production. Both packaging formats contain the same component with identical electrical and mechanical specifications.

Q: Why is TPS77001DBVT marked as Last Time Buy?

A: Last Time Buy designation indicates Texas Instruments is discontinuing this specific part number variant. Customers requiring this component should transition to the TPS77001DBVR, which maintains identical performance specifications and active production status.

Q: Are there any compliance differences between the two parts?

A: No. Both TPS77001DBVT and TPS77001DBVR carry ROHS3 compliance and REACH unaffected status. Moisture sensitivity level is identical at MSL 1 (Unlimited). Both parts meet current regulatory requirements for electronic component manufacturing and distribution.

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

A: Substitution is determined by matching output configuration (Positive), output type (Adjustable), voltage specifications (10V input maximum, 1.2V to 5.5V output), current rating (50mA), quiescent current (28 µA), PSRR (60dB at 1kHz), protection features (Over Current, Over Temperature, Reverse Polarity), package type (SOT-23-5), and operating temperature range (-40°C to 125°C).
