Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS77030DBVRG4 are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents (Direct Substitutes): Parts that maintain identical electrical specifications across all critical parameters including output voltage (3V), output current (50mA), input voltage maximum (10V), voltage dropout (0.12V @ 50mA), quiescent current (28 µA), control features (Enable), protection features (Over Current, Over Temperature, Reverse Polarity), operating temperature range (-40°C ~ 125°C), and package type (SOT-23-5). These parts differ only in packaging format (Tape & Reel vs. Cut Tape) or product status (Active vs. Discontinued).

Manufacturer Recommended Substitutes: Parts from alternative manufacturers (ABLIC Inc.) that share the same output voltage (3V), input voltage maximum (10V), package type (SOT-23-5), control features (Enable), operating temperature range (-40°C ~ 85°C), and RoHS compliance. These parts have higher output current capability (150mA vs. 50mA) and different dropout voltage and quiescent current specifications, making them suitable for applications requiring higher current delivery.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

Select TPS77030DBVR or TPS77030DBVT for applications requiring exact electrical and functional equivalence to the TPS77030DBVRG4. TPS77030DBVR is available in Tape & Reel packaging with Active product status, providing the most reliable long-term availability. TPS77030DBVT is available in Cut Tape format with Last Time Buy status, suitable for immediate procurement but not recommended for new long-term production commitments.

For Enhanced Performance (Higher Current Capability):

Select TPS79030DBVR or TPS79030DBVT when applications can accommodate improved PSRR performance (85dB vs. 60dB at 1kHz) while maintaining identical output voltage, input voltage, dropout voltage, quiescent current, and protection features. Both parts maintain Active product status and full operating temperature range (-40°C ~ 125°C).

For Alternative Manufacturer Solutions (Higher Current Output):

Select S-1200B30-M5T1U (ABLIC Inc.) for applications requiring higher output current (150mA vs. 50mA) with significantly reduced quiescent current (1 µA vs. 28 µA). This part is Active and suitable for new designs. The S-1200B30-M5T1G variant is available but marked Not For New Designs. Both ABLIC parts have reduced operating temperature range (-40°C ~ 85°C) and lower protection feature set (Over Current only, without Over Temperature and Reverse Polarity protection).

Frequently Asked Questions (FAQ)

Q: Can TPS77030DBVR directly replace TPS77030DBVRG4?

A: Yes. TPS77030DBVR is a parametric equivalent with identical electrical specifications including 3V output, 50mA current, 0.12V dropout, 28 µA quiescent current, and full protection features. The only difference is packaging format (Tape & Reel vs. the original format) and Active product status, making it the preferred direct replacement.

Q: What is the difference between TPS77030DBVT and TPS77030DBVR?

A: Both are parametric equivalents with identical electrical specifications. TPS77030DBVT is supplied in Cut Tape format with Last Time Buy status, while TPS77030DBVR is supplied in Tape & Reel format with Active status. For new production, TPS77030DBVR is recommended due to its Active product status.

Q: Can I use TPS79030DBVR instead of TPS77030DBVRG4?

A: Yes, with the following consideration: TPS79030DBVR maintains all critical electrical parameters (3V output, 50mA current, 0.12V dropout, 28 µA quiescent current, Enable control, and full protection features) but offers improved PSRR performance (85dB vs. 60dB at 1kHz). It is suitable for applications where enhanced noise rejection is beneficial.

Q: Why would I choose S-1200B30-M5T1U over Texas Instruments parts?

A: S-1200B30-M5T1U provides three times higher output current (150mA vs. 50mA) and significantly lower quiescent current (1 µA vs. 28 µA), making it suitable for applications requiring higher current delivery or extended battery life. However, it has a reduced operating temperature range (-40°C ~ 85°C vs. -40°C ~ 125°C) and provides only Over Current protection without Over Temperature and Reverse Polarity protection.

Q: Are all substitute parts in the same SOT-23-5 package?

A: Yes. All substitute parts listed use the SOT-23-5 package (SC-74A, SOT-753 case), ensuring identical PCB footprint and pin compatibility with the TPS77030DBVRG4.

Q: What is the difference between packaging formats (Tape & Reel vs. Cut Tape)?

A: Tape & Reel (TR) packaging is supplied on continuous tape suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging is supplied as individual segments cut from the tape, suitable for manual assembly or smaller production runs. Both formats use the same SOT-23-5 package and are electrically identical.

Q: Is RoHS compliance maintained across all substitute parts?

A: Yes. All substitute parts listed are ROHS3 Compliant, maintaining environmental and regulatory compliance equivalent to the original TPS77030DBVRG4.
