Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): TPS76925DBVR is the primary substitute for TPS76925DBVT. Both devices share identical electrical parameters and are manufactured by Texas Instruments. The TPS76925DBVR is in Active product status, ensuring continued availability and support. The difference in packaging format (Cut Tape & Digi-Reel versus Cut Tape) does not affect electrical performance and accommodates various procurement workflows.

For Automotive Applications: TPS76925QDBVRQ1 and TPS76925QDBVRG4Q1 are qualified to AEC-Q100 automotive standards and maintain identical electrical specifications. These variants are suitable for automotive-grade designs requiring regulatory compliance. Both are available in Tape & Reel format and carry Active product status.

For Enhanced Noise Performance: TPS78925DBVR and TPS78925DBVT offer improved PSRR of 85dB at 1kHz compared to the 60dB specification of the TPS76925DBVT. These variants are electrically compatible and suitable for applications requiring superior power supply rejection ratio. Both are in Active product status. Selection between DBVR (Cut Tape & Digi-Reel) and DBVT (Tape & Reel) depends on procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can TPS76925DBVR directly replace TPS76925DBVT? A: Yes. Both parts are parametrically identical with matching output voltage (2.5V), output current (100mA), input voltage rating (10V), quiescent current (28 µA), and package (SOT-23-5). The TPS76925DBVR is in Active product status, making it the recommended direct replacement.

Q: What is the difference between TPS76925 and TPS78925 variants? A: The primary difference is PSRR performance. TPS76925 devices provide 60dB PSRR at 1kHz, while TPS78925 devices provide 85dB PSRR at 1kHz. All other electrical and mechanical parameters remain identical. Selection depends on noise rejection requirements for the application.

Q: Are automotive-qualified variants (QDBVR) compatible with standard designs? A: Yes. Automotive-qualified variants (TPS76925QDBVRQ1 and TPS76925QDBVRG4Q1) maintain identical electrical specifications and package compatibility with standard variants. They include additional AEC-Q100 qualification but do not require design changes for implementation in non-automotive applications.

Q: What is the difference between Cut Tape and Tape & Reel packaging? A: Both formats contain identical components in the same SOT-23-5 package. Cut Tape (CT) and Digi-Reel are suitable for lower-volume or manual assembly processes. Tape & Reel (TR) format is optimized for high-volume automated assembly. Electrical performance is unaffected by packaging format.

Q: Can I use TPS78925DBVT in place of TPS76925DBVT? A: Yes, with the understanding that TPS78925DBVT provides enhanced PSRR (85dB versus 60dB). This is a performance upgrade with no electrical incompatibility. The device is pin-compatible and functionally equivalent for all specified parameters.

Q: Is the TPS76925DBVT still available? A: The TPS76925DBVT is classified as Last Time Buy, indicating end-of-life status. TPS76925DBVR is the recommended active alternative with identical specifications and continued manufacturer support.
