TPS76930DBVR Equivalent & Substitute Parts

Part Overview

The TPS76930DBVR is a linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) component. It delivers a fixed 3V output at 100mA with a maximum dropout voltage of 0.23V, housed in a SOT-23-5 surface mount package. The device is currently in Active product status with 652,600 units in stock.

Substitute parts are necessary when the primary part reaches end-of-life, inventory constraints occur, or when design requirements demand alternative electrical characteristics such as higher output current, improved PSRR performance, or automotive-grade qualification.

Substitute Part Grouping Explanation

Substitute parts for the TPS76930DBVR are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents (Direct Substitutes): Parts that maintain identical or functionally equivalent electrical specifications across all critical parameters: 3V fixed output, 100mA output current, 10V maximum input voltage, SOT-23-5 package, and -40°C to 125°C operating temperature range. These parts differ only in packaging format (Cut Tape vs. Tape & Reel) or product status (Active vs. Last Time Buy).

Manufacturer Recommended Alternatives: Parts that share the same output voltage (3V), package type (SOT-23-5), and core functionality but deviate in one or more electrical parameters such as output current capacity, quiescent current, PSRR performance, or operating temperature range. These alternatives are suitable when design specifications allow for parameter variations.

Key substitution criteria:

Output voltage: 3V (fixed)
Package / Case: SC-74A, SOT-753 (SOT-23-5)
Mounting type: Surface Mount
Output configuration: Positive, Fixed
Number of regulators: 1

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

TPS76930QDBVRG4Q1 is the preferred direct substitute when the primary part is unavailable. It maintains all electrical parameters of the TPS76930DBVR while offering Active product status and higher inventory availability (6,684 units). This part includes AEC-Q100 automotive qualification, making it suitable for applications requiring automotive-grade components.

TPS78930DBVR and TPS78930DBVT are functionally equivalent alternatives with improved PSRR performance (85dB vs. 60dB at 1kHz). Both maintain 100mA output current and identical dropout voltage specifications. TPS78930DBVR is available in Tape & Reel packaging with 7,180 units in stock, while TPS78930DBVT is available in Cut Tape format with 5,603 units.

TPS76930DBVT is a direct parametric equivalent in Cut Tape packaging but carries Last Time Buy status, indicating limited future availability.

For Applications Allowing Parameter Variation:

LD2980ABM30TR (STMicroelectronics) is suitable when output current requirements are reduced to 50mA or lower. It offers comparable dropout voltage (0.225V @ 50mA) and maintains the -40°C to 125°C operating range. Higher quiescent current (150 µA) should be evaluated for battery-powered applications.

S-1200B30-M5T1U (ABLIC Inc.) is recommended when higher output current (150mA) is required and operating temperature does not exceed 85°C. This part offers superior quiescent current performance (1 µA) and lower dropout voltage (0.21V @ 100mA), beneficial for low-power applications. Active product status ensures long-term availability with 11,800 units in stock.

S-1200B30-M5T1G carries Not For New Designs status and should be avoided for new product development.

Frequently Asked Questions (FAQ)

Q: Can TPS76930QDBVRG4Q1 replace TPS76930DBVR in existing designs?

A: Yes. TPS76930QDBVRG4Q1 is a parametric equivalent with identical electrical specifications (3V output, 100mA current, 0.23V dropout voltage, 60dB PSRR). The only difference is packaging format (Tape & Reel vs. Cut Tape) and the addition of AEC-Q100 automotive qualification. No circuit modifications are required.

Q: What is the difference between TPS76930DBVR and TPS78930DBVR?

A: Both parts deliver 3V at 100mA with identical dropout voltage (0.23V @ 100mA) and operating temperature range (-40°C to 125°C). The primary difference is PSRR performance: TPS78930DBVR provides 85dB at 1kHz compared to 60dB for TPS76930DBVR. Select TPS78930DBVR when lower noise output is required.

Q: Is LD2980ABM30TR a suitable replacement for 100mA applications?

A: LD2980ABM30TR is not recommended as a direct replacement because it is rated for only 50mA output current, compared to the 100mA specification of TPS76930DBVR. Use this part only when your application requires 50mA or less.

Q: Can S-1200B30-M5T1U be used in designs requiring -40°C to 125°C operation?

A: No. S-1200B30-M5T1U is rated for -40°C to 85°C operation only. It is not suitable for applications requiring the full -40°C to 125°C temperature range of the TPS76930DBVR.

Q: Why is S-1200B30-M5T1G marked as Not For New Designs?

A: S-1200B30-M5T1G carries Not For New Designs status, indicating the manufacturer has discontinued active support for this part. Use S-1200B30-M5T1U (Active status) for new designs requiring the S-1200 series specifications.

Q: What packaging formats are available for TPS76930DBVR substitutes?

A: Substitutes are available in two packaging formats: Cut Tape (CT) & Digi-Reel® for lower-volume applications, and Tape & Reel (TR) for high-volume production. Both formats use the same SOT-23-5 package. Select based on your procurement and assembly requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH Unaffected status, consistent with the TPS76930DBVR specifications.
