TPS77030DBVT Equivalent & Substitute Parts

Part Overview

The TPS77030DBVT is a linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) component. It delivers a fixed 3V output at 50mA with a maximum dropout voltage of 0.12V, housed in an SOT-23-5 surface mount package. The device features enable control, over-current protection, over-temperature protection, and reverse polarity protection, operating across -40°C to 125°C.

The TPS77030DBVT carries a Last Time Buy product status, indicating it is being phased out. Identifying equivalent and substitute parts ensures design continuity and supply chain reliability for applications requiring 3V linear regulation at 50mA output capacity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS77030DBVT are categorized based on strict parametric equivalence and manufacturer recommendations. The primary substitution criteria are:

Parametric Equivalents (Direct Substitutes): Parts maintaining identical output voltage (3V), output current (50mA), input voltage rating (10V), dropout voltage (0.12V @ 50mA), quiescent current (28 µA), package type (SOT-23-5), and operating temperature range (-40°C to 125°C). These parts differ only in packaging format (Cut Tape vs. Tape & Reel) or minor product status variations.

Manufacturer Recommended Alternatives: Parts with higher output current capability (150mA) and compatible voltage specifications, offered by alternative manufacturers. These provide enhanced current delivery while maintaining the same 3V output, SOT-23-5 package, and core protection features. Operating temperature ranges may vary.

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalents: TPS77030DBVR, TPS79030DBVR, and TPS79030DBVT are direct substitutes from Texas Instruments with Active product status. TPS77030DBVR maintains identical electrical specifications and differs only in packaging format (Tape & Reel vs. Cut Tape). TPS79030DBVR and TPS79030DBVT offer improved PSRR performance (85dB vs. 60dB at 1kHz) while maintaining all other critical parameters. All three are ROHS3 compliant and REACH unaffected.

Alternative Manufacturer Options: S-1200B30-M5T1U and S-L2980A30MC-TF-U from ABLIC Inc. provide higher output current capability (150mA) in the same SOT-23-5 package. S-L2980A30MC-TF-U offers superior dropout voltage performance (0.15V @ 50mA) compared to the original part. Both are Active status products, ROHS3 compliant, and REACH unaffected. Operating temperature range is reduced to -40°C to 85°C. S-1200B30-M5T1G carries Not For New Designs status and should be avoided for new applications.

All substitute parts maintain the same 3V fixed output voltage, SOT-23-5 package footprint, and surface mount mounting type, ensuring mechanical and electrical compatibility within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can TPS77030DBVR directly replace TPS77030DBVT? A: Yes. Both parts are electrically identical with matching output voltage (3V), output current (50mA), dropout voltage (0.12V @ 50mA), quiescent current (28 µA), and operating temperature range (-40°C to 125°C). The difference is packaging format: TPS77030DBVT is supplied in Cut Tape, while TPS77030DBVR is supplied in Tape & Reel. Both are ROHS3 compliant.

Q: What is the advantage of TPS79030DBVR or TPS79030DBVT over the original TPS77030DBVT? A: The TPS79030 variants provide improved Power Supply Rejection Ratio (PSRR) of 85dB at 1kHz compared to 60dB for the TPS77030. All other electrical parameters remain identical. Both are Active status products from Texas Instruments.

Q: Can I use S-1200B30-M5T1U as a substitute if my application requires only 50mA output? A: Yes. The S-1200B30-M5T1U is rated for 150mA output current, which exceeds the 50mA requirement of the original part. It maintains the same 3V output voltage and SOT-23-5 package. However, the operating temperature range is limited to -40°C to 85°C (versus -40°C to 125°C for the TPS77030DBVT), and dropout voltage is higher at 0.21V @ 100mA. Verify temperature requirements before selection.

Q: Why is S-1200B30-M5T1G marked as Not For New Designs? A: S-1200B30-M5T1G carries a Not For New Designs product status, indicating it is being phased out by the manufacturer. For new applications, use S-1200B30-M5T1U, which is Active status and offers the same electrical specifications in Tape & Reel packaging.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts (TPS77030DBVR, TPS79030DBVR, TPS79030DBVT, S-1200B30-M5T1G, S-1200B30-M5T1U, and S-L2980A30MC-TF-U) are ROHS3 compliant and REACH unaffected.

Q: What is the difference between Cut Tape and Tape & Reel packaging? A: Cut Tape (CT) packaging supplies components on individual tape segments, suitable for lower-volume applications. Tape & Reel (TR) packaging supplies components on continuous reels, optimized for high-volume automated assembly. Both formats contain identical components; the difference is in supply and handling format.

Q: Can I use S-L2980A30MC-TF-U if my circuit operates at temperatures above 85°C? A: No. The S-L2980A30MC-TF-U is rated for -40°C to 85°C operating temperature. If your application requires operation above 85°C, use TPS77030DBVR, TPS79030DBVR, or TPS79030DBVT, which are rated to 125°C.
