Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS76130DBVR are classified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Output voltage: 3V fixed output
• Output current capability: 100mA or greater
• Package type: SOT-23-5 (SC-74A, SOT-753)
• Input voltage rating: 16V or greater
• Operating temperature range: -40°C ~ 125°C
• Surface mount mounting type
• Control features: Enable function
• Protection features: Over Current and Over Temperature minimum

Substitution Categories:

Category 1 - Parametric Equivalent (Identical Specifications): Parts with matching output voltage, current rating, and electrical characteristics. These provide direct replacement capability.

Category 2 - Functional Equivalent with Enhanced Performance: Parts with 3V output, equal or greater current capacity, improved electrical characteristics (lower dropout voltage, lower quiescent current), and active product status. These offer superior performance while maintaining full compatibility.

Category 3 - Functional Equivalent with Different Output Voltage: Parts with different fixed output voltages (5V) in identical packaging. These require circuit design consideration but share mechanical and thermal characteristics.

Category 4 - Functional Equivalent with Lower Current Rating: Parts with 3V output but reduced current capacity (80mA). These are suitable only for applications with lower current requirements.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): TPS76130DBVT is the primary recommendation. This part maintains identical electrical specifications and packaging while offering active product status, ensuring continued availability and manufacturing support. Both parts are Texas Instruments products with ROHS3 compliance and unlimited moisture sensitivity rating.

For Enhanced Performance with 3V Output: TPS7A2430DBVR provides superior performance characteristics including doubled output current capacity (200mA), improved dropout voltage (0.25V vs 0.28V), significantly lower quiescent current (4.5 µA vs 115 µA), and higher input voltage rating (18V vs 16V). This part is recommended for new designs or applications where improved efficiency is beneficial. Active product status ensures long-term supply availability.

For Current-Limited Applications (3V Output): MIC5225-3.0YM5-TR offers 150mA output current with 3V fixed output in SOT-23-5 packaging. This Microchip Technology part provides intermediate current capacity between the original 100mA and the 200mA TPS7A2430DBVR option. Active product status and ROHS3 compliance are confirmed.

For Lower Current Requirements (3V Output): MIC5203-3.0YM5-TR is suitable only for applications requiring 80mA or less. Higher dropout voltage (0.6V) and quiescent current (750 µA) make this option less efficient than alternatives. Use only when current requirement does not exceed 80mA.

For 5V Output Applications: LD2981ABM50TR and LD2981CM50TR are functionally equivalent STMicroelectronics parts with 5V fixed output, 100mA current capacity, and SOT-23-5 packaging. These parts are not direct replacements for 3V applications but serve as alternatives for designs requiring 5V regulation. Both variants are active products with ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can TPS76130DBVT be used as a direct replacement for TPS76130DBVR? A: Yes. TPS76130DBVT is a parametric equivalent with identical electrical specifications, output voltage (3V), output current (100mA), dropout voltage, quiescent current, and SOT-23-5 packaging. The primary difference is product status: TPS76130DBVT is active while TPS76130DBVR is Last Time Buy. Both are Texas Instruments products with identical compliance certifications.

Q: What is the advantage of using TPS7A2430DBVR over TPS76130DBVR? A: TPS7A2430DBVR provides enhanced performance with doubled output current (200mA vs 100mA), lower dropout voltage (0.25V vs 0.28V), and significantly lower quiescent current (4.5 µA vs 115 µA). It maintains 3V output voltage and SOT-23-5 packaging while offering active product status. These improvements result in better efficiency and thermal performance.

Q: Can I use MIC5203-3.0YM5-TR as a substitute for TPS76130DBVR? A: MIC5203-3.0YM5-TR is not recommended as a primary substitute. While it provides 3V output in SOT-23-5 packaging, its 80mA current rating is below the original 100mA specification. Additionally, dropout voltage (0.6V) and quiescent current (750 µA) are significantly higher, resulting in reduced efficiency. Use only if application current requirement does not exceed 80mA.

Q: Are LD2981 parts compatible with TPS76130DBVR? A: LD2981ABM50TR and LD2981CM50TR are not direct substitutes. These STMicroelectronics parts provide 5V fixed output instead of 3V, requiring circuit design changes. They are suitable only for applications designed for 5V regulation. Both share SOT-23-5 packaging and 100mA current capacity with the original part.

Q: What is the difference between LD2981ABM50TR and LD2981CM50TR? A: Both parts are functionally identical with 5V output, 100mA current capacity, and SOT-23-5 packaging. The primary difference is packaging format: LD2981ABM50TR is supplied in Cut Tape (CT) & Digi-Reel format, while LD2981CM50TR is supplied in Tape & Reel (TR) format. Electrical specifications and performance characteristics are identical.

Q: Why is TPS76130DBVR marked as Last Time Buy? A: Last Time Buy status indicates the manufacturer has discontinued this product line. Existing inventory is available for final orders, but no future production is planned. This necessitates identifying equivalent or substitute parts for design continuity and long-term supply chain planning.

Q: Can I use MIC5225-3.0YM5-TR for applications requiring exactly 100mA? A: MIC5225-3.0YM5-TR provides 150mA output current, which exceeds the 100mA requirement. This part is suitable for applications requiring up to 150mA at 3V output. It offers improved current capacity margin compared to the original TPS76130DBVR while maintaining identical output voltage and SOT-23-5 packaging.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts listed (TPS76130DBVT, TPS7A2430DBVR, MIC5203-3.0YM5-TR, MIC5225-3.0YM5-TR, LD2981ABM50TR, and LD2981CM50TR) are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), matching the original TPS76130DBVR compliance status.

Q: What is the operating temperature range for all substitute parts? A: All substitute parts maintain the same operating temperature range as the original TPS76130DBVR: -40°C to 125°C. This ensures thermal compatibility across all equivalent and substitute options.
