Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS76901SDBVTEP is determined by the following critical parameters:

• Output configuration (Positive)
• Output type (Adjustable)
• Number of regulators (1)
• Maximum input voltage (10V)
• Minimum output voltage (1.2V)
• Output current capability (100mA)
• Package type (SOT-23-5)
• Protection features (Over Current, Over Temperature, Reverse Polarity)
• Control features (Enable)

The TPS76901QDBVRG4Q1 qualifies as a manufacturer-recommended substitute. Both parts share identical functional specifications for output configuration, regulation type, current delivery, and protection mechanisms. Both are housed in the same SOT-23-5 package and maintain compatibility with existing PCB layouts. The primary distinction lies in product status and operating temperature range, which are documented in the parameter comparison table below.

Engineering Selection Recommendations

The TPS76901QDBVRG4Q1 is the manufacturer-recommended substitute for the TPS76901SDBVTEP. Both devices maintain functional equivalence across all critical electrical parameters including output voltage range, current delivery, quiescent current, and protection mechanisms.

Key considerations for selection:

The TPS76901QDBVRG4Q1 carries Active product status, ensuring continued availability and supply chain support, whereas the TPS76901SDBVTEP is Last Time Buy. The substitute part includes Automotive grade qualification and AEC-Q100 certification, indicating suitability for automotive applications with enhanced reliability requirements.

The TPS76901QDBVRG4Q1 supports a maximum output voltage of 5.5V compared to 4.5V for the main part, providing expanded output voltage capability within the same package footprint. Operating temperature range differs: the substitute operates from -40°C to 125°C versus -55°C to 150°C for the original part. Applications requiring the extended temperature range of the TPS76901SDBVTEP must verify that the substitute's temperature specification meets system requirements.

Both parts are ROHS3 compliant, REACH unaffected, and housed in identical SOT-23-5 packages, ensuring direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the TPS76901QDBVRG4Q1 directly replace the TPS76901SDBVTEP in existing designs?

A: Yes, for applications operating within the temperature range of -40°C to 125°C and output voltage requirements up to 5.5V. The substitute maintains identical package geometry, pin configuration, and functional specifications for output current, quiescent current, and protection features. Verify that your application's operating temperature and maximum output voltage requirements fall within the substitute's specifications.

Q: What is the primary difference between these two parts?

A: The TPS76901QDBVRG4Q1 is an active, automotive-qualified variant with AEC-Q100 certification, while the TPS76901SDBVTEP is Last Time Buy. The substitute supports a higher maximum output voltage (5.5V vs. 4.5V) and operates over a narrower temperature range (-40°C to 125°C vs. -55°C to 150°C).

Q: Are both parts available in the same package?

A: Yes. Both the TPS76901SDBVTEP and TPS76901QDBVRG4Q1 are supplied in SOT-23-5 packages (SC-74A, SOT-753 case designation), ensuring identical footprint and pin compatibility on PCBs.

Q: Does the TPS76901QDBVRG4Q1 meet automotive standards?

A: Yes. The TPS76901QDBVRG4Q1 is automotive-grade and qualified to AEC-Q100, making it suitable for automotive applications requiring enhanced reliability and quality assurance.

Q: What happens if my application requires the full temperature range of the original part?

A: If your design requires operation below -40°C or above 125°C, the TPS76901QDBVRG4Q1 does not meet those specifications. In such cases, alternative parts from the TPS76901 series or other manufacturers must be evaluated based on your specific temperature requirements.

Q: Are there any compliance or regulatory differences?

A: Both parts are ROHS3 compliant and REACH unaffected. The TPS76901QDBVRG4Q1 carries additional automotive qualification (AEC-Q100), which may be required for automotive applications but is not mandatory for general industrial or consumer applications.
