TPS79301DBVREP Equivalent & Substitute Parts

Part Overview

The TPS79301DBVREP is a linear voltage regulator IC from Texas Instruments designed for positive adjustable output applications. This Surface Mount device in SOT-23-6 package delivers 200mA output current with adjustable voltage regulation from 1.22V to 5.5V. The part is Active status and widely used in power management circuits requiring low-dropout regulation with integrated protection features including over-current, over-temperature, reverse polarity, and under-voltage lockout protection.

Substitute parts are necessary when the primary part number becomes unavailable due to inventory constraints, supply chain disruptions, or when alternative packaging formats better suit manufacturing requirements while maintaining identical electrical performance.

Substitute Part Grouping Explanation

Substitution eligibility for the TPS79301DBVREP is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Output Configuration: Positive
• Output Type: Adjustable
• Voltage - Input (Max): 5.5V
• Voltage - Output (Min/Fixed): 1.22V
• Voltage - Output (Max): 5.5V
• Current - Output: 200mA
• Package / Case: SOT-23-6
• Operating Temperature: -40°C ~ 125°C
• Protection Features: Over Current, Over Temperature, Reverse Polarity, Under Voltage Lockout (UVLO)

Mechanical Equivalence Requirements:

• Mounting Type: Surface Mount
• Supplier Device Package: SOT-23-6

Compliance Requirements:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All substitute parts listed maintain identical electrical and mechanical specifications. Packaging format differences (Tape & Reel vs. Cut Tape & Digi-Reel) do not affect functional equivalence and are determined by manufacturing and procurement requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Identical Specifications): TPS79301DBVT is the direct equivalent with identical electrical performance and standard grade qualification. Selection between TPS79301DBVREP and TPS79301DBVT depends solely on packaging format requirements (Tape & Reel vs. alternative reel format).

Automotive Grade Alternatives: TPS79301DBVRG4Q1 and TPS79301DBVRQ1 are AEC-Q100 qualified automotive-grade variants of the TPS79301 base product. These parts maintain identical electrical specifications to the standard grade TPS79301DBVREP but include automotive qualification. Selection of automotive-grade parts is required only when the application demands AEC-Q100 compliance.

TPS73001 Series (Parametric Equivalent): TPS73001DBVR and TPS73001DBVT are parametric equivalents with identical voltage and current specifications. The primary difference is quiescent current: TPS73001 series draws 250 µA versus 220 µA for TPS79301 series. Both maintain ROHS3 compliance and identical operating temperature range. Selection between TPS79301 and TPS73001 series is determined by power consumption requirements in standby or low-current operating modes.

Product Status: All listed substitute parts maintain Active status with Texas Instruments, ensuring continued availability and support.

Frequently Asked Questions (FAQ)

Q: Can TPS79301DBVT replace TPS79301DBVREP directly? A: Yes. TPS79301DBVT is electrically and mechanically identical to TPS79301DBVREP. The difference is packaging format. Both are standard grade, SOT-23-6 package, with 200mA output and identical voltage regulation specifications.

Q: What is the difference between TPS79301 and TPS73001 series? A: Both series are parametrically equivalent with identical voltage input/output ranges and 200mA output current. The TPS73001 series has higher quiescent current (250 µA vs. 220 µA). Selection depends on application power consumption requirements. Both are ROHS3 compliant and operate across -40°C to 125°C.

Q: When should I use automotive-grade parts TPS79301DBVRG4Q1 or TPS79301DBVRQ1? A: Automotive-grade variants are required only when the application demands AEC-Q100 qualification. Electrical performance is identical to standard-grade TPS79301DBVREP. Use standard-grade parts for non-automotive applications.

Q: Does packaging format affect electrical performance? A: No. Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging formats are mechanical differences only. Electrical specifications remain identical. Packaging selection is determined by manufacturing equipment and procurement processes.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of TPS79301DBVREP.

Q: Can I use TPS73001DBVR in place of TPS79301DBVREP in high-frequency switching applications? A: Electrical specifications are identical for voltage regulation and current output. PSRR specifications differ slightly (68dB at 100Hz for TPS73001 vs. 70dB at 100Hz for TPS79301). Application-specific performance testing is required to confirm suitability for high-frequency noise rejection requirements.
