Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS77025DBVT are classified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Output voltage: 2.5V fixed
• Package type: SOT-23-5 (SC-74A, SOT-753)
• Output configuration: Positive
• Mounting type: Surface Mount
• Control features: Enable function
• RoHS3 compliance and MSL Level 1

Substitution Categories:

Parametric Equivalents (Direct Replacements): Parts with identical electrical specifications including 50mA output current, 10V maximum input voltage, 28 µA quiescent current, and equivalent protection features. These include TPS77025DBVR, TPS79025DBVT, and TPS79025DBVR, which differ only in packaging format (tape & reel vs. cut tape) or minor performance enhancements (PSRR).

Manufacturer Recommended Upgrades: Parts offering enhanced performance while maintaining core compatibility. TPS7A2425DBVR provides 200mA output current (4x higher), improved quiescent current (4.5 µA vs. 28 µA), and higher input voltage rating (18V vs. 10V). S-1200B25-M5T1U and S-L2980A25MC-TF-U offer 150mA output current with superior quiescent current performance (1 µA), though from alternative manufacturers (ABLIC Inc.).

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Parametric Equivalents): TPS77025DBVR, TPS79025DBVT, and TPS79025DBVR are direct functional replacements with identical electrical performance. All three are active products with ROHS3 compliance and MSL Level 1 rating. Selection between these three depends on packaging availability: TPS77025DBVR is supplied in cut tape format, while TPS79025DBVT and TPS79025DBVR are supplied in tape & reel format. TPS79025 variants offer improved PSRR (85dB vs. 60dB at 1kHz), providing superior noise rejection in noise-sensitive applications.

Performance-Enhanced Alternatives: TPS7A2425DBVR from Texas Instruments provides 4x higher output current (200mA vs. 50mA) with significantly lower quiescent current (4.5 µA vs. 28 µA) and higher input voltage rating (18V vs. 10V). This part is suitable for applications requiring higher current delivery or extended input voltage range while maintaining the same 2.5V output and SOT-23-5 package. Product status is active with full ROHS3 compliance.

Alternative Manufacturer Options: S-1200B25-M5T1U and S-L2980A25MC-TF-U from ABLIC Inc. offer 150mA output current with exceptional quiescent current performance (1 µA). These parts are active products with ROHS3 compliance. Operating temperature range is limited to -40°C ~ 85°C compared to -40°C ~ 125°C for Texas Instruments variants. Selection of ABLIC parts is appropriate when ultra-low quiescent current is prioritized and the reduced temperature range is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can TPS77025DBVR directly replace TPS77025DBVT? A: Yes. TPS77025DBVR is a parametric equivalent with identical electrical specifications. The difference is packaging format: DBVR is supplied in cut tape format while DBVT is supplied in tape & reel format. Both are active products with equivalent compliance certifications.

Q: What is the advantage of TPS7A2425DBVR over the original TPS77025DBVT? A: TPS7A2425DBVR provides four times higher output current (200mA vs. 50mA), significantly lower quiescent current (4.5 µA vs. 28 µA for reduced power consumption), and higher maximum input voltage (18V vs. 10V). It maintains the same 2.5V output voltage and SOT-23-5 package footprint, making it suitable for applications requiring higher current delivery or extended input voltage range.

Q: Are ABLIC parts (S-1200B25-M5T1U and S-L2980A25MC-TF-U) compatible with the original design? A: ABLIC parts are functionally compatible in terms of output voltage (2.5V), package type (SOT-23-5), and control features. Key differences include 150mA output current (vs. 50mA), exceptional quiescent current (1 µA vs. 28 µA), and reduced operating temperature range (-40°C ~ 85°C vs. -40°C ~ 125°C). Compatibility depends on whether your application requires the higher current capability and can operate within the lower temperature range.

Q: Why is the TPS77025DBVT marked as obsolete? A: The TPS77025DBVT is classified as obsolete by Texas Instruments. Active alternatives with identical or superior specifications are available, including TPS77025DBVR, TPS79025 variants, and TPS7A2425DBVR. New designs should use active product variants to ensure long-term supply availability and manufacturing support.

Q: What is the difference between TPS79025DBVT and TPS79025DBVR? A: Both are parametric equivalents with identical electrical specifications. The difference is packaging format: DBVT is supplied in tape & reel format while DBVR is also supplied in tape & reel format. Both offer improved PSRR (85dB at 1kHz) compared to the original TPS77025DBVT (60dB at 1kHz).

Q: Can I use TPS7A2425DBVR in a design originally specified for 50mA output? A: Yes. TPS7A2425DBVR is backward compatible for applications requiring 50mA or less output current. The higher current rating (200mA) does not affect operation at lower current levels. The improved quiescent current (4.5 µA vs. 28 µA) provides additional power efficiency benefit. Verify that the higher input voltage rating (18V vs. 10V) does not conflict with your circuit design.

Q: What are the packaging differences between the substitute parts? A: All substitute parts use the same SOT-23-5 package (SC-74A, SOT-753) with identical PCB footprint. Differences exist only in supply format: cut tape (CT), tape & reel (TR), or Digi-Reel format. These differences affect procurement and handling but do not impact electrical performance or board-level compatibility.
