Key Parameters

Substitute Part Grouping Explanation

Substitution for the TPS77012DBVR is determined by alignment across the following critical parameters:

Electrical Compatibility Criteria:

• Output configuration (Positive)
• Output type (Fixed or Adjustable with fixed output capability)
• Output voltage (1.2V fixed)
• Current capacity (50mA minimum)
• Maximum input voltage (10V or higher)
• Quiescent current (28 µA)
• PSRR (60dB at 1kHz)
• Protection features (Over Current, Over Temperature, Reverse Polarity)
• Operating temperature range (-40°C ~ 125°C)

Mechanical Compatibility Criteria:

• Package type (SOT-23-5 / SC-74A, SOT-753)
• Mounting type (Surface Mount)

Compliance Criteria:

• RoHS3 compliance
• MSL rating (1 - Unlimited)

Substitutes are classified into two categories:

1. MFR Recommended Substitute: TPS77001DBVR - Functionally compatible with adjustable output capability, allowing fixed 1.2V configuration while offering design flexibility for future modifications.

2. Parametric Equivalent: TPS77012DBVT - Identical electrical and mechanical specifications with alternative packaging format (Tape & Reel vs. Cut Tape).

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Long-Term Supply: Select TPS77001DBVR. This part is in Active product status with higher inventory availability (16,295 pcs vs. 4,300 pcs for the main part). The adjustable output capability provides design flexibility while maintaining full electrical and mechanical compatibility at the 1.2V fixed output configuration. ROHS3 compliance and MSL-1 rating ensure regulatory and environmental compatibility.

For Existing Inventory or Short-Term Replacement: TPS77012DBVT serves as a parametric equivalent with identical electrical specifications and package footprint. However, this part is classified as Obsolete, making it unsuitable for long-term supply chain planning. Use only when packaging format (Tape & Reel) is specifically required and inventory is available.

Product Status Consideration: The main part (TPS77012DBVR) is Last Time Buy, indicating imminent production discontinuation. Transition to TPS77001DBVR is recommended to ensure uninterrupted supply and design continuity.

Frequently Asked Questions (FAQ)

Q: Can TPS77001DBVR directly replace TPS77012DBVR in existing designs? A: Yes. Both devices share identical electrical specifications (50mA output, 1.2V fixed capability, 28 µA quiescent current, 60dB PSRR, protection features) and the same SOT-23-5 package footprint. The adjustable output feature of TPS77001DBVR does not affect fixed 1.2V operation when configured appropriately.

Q: What is the difference between TPS77012DBVR and TPS77012DBVT? A: These parts are parametrically identical with the same electrical specifications and package type. The difference is packaging format: TPS77012DBVR is supplied in Cut Tape (CT), while TPS77012DBVT is supplied in Tape & Reel (TR). TPS77012DBVT is Obsolete and should not be selected for new designs.

Q: Why is TPS77001DBVR recommended over TPS77012DBVT? A: TPS77001DBVR is in Active product status with significantly higher inventory (16,295 pcs), ensuring long-term availability. TPS77012DBVT is Obsolete, making it unsuitable for sustained production. Both offer equivalent electrical performance, but only TPS77001DBVR provides supply chain reliability.

Q: Are there any circuit design changes required when switching to TPS77001DBVR? A: No circuit modifications are required. TPS77001DBVR operates identically to TPS77012DBVR at 1.2V fixed output. The adjustable output feature is not utilized in fixed-output applications and does not affect circuit behavior.

Q: Do all three parts meet the same compliance standards? A: Yes. TPS77012DBVR, TPS77001DBVR, and TPS77012DBVT are all ROHS3 compliant with MSL-1 (Unlimited) moisture sensitivity rating, ensuring equivalent environmental and regulatory compliance.

Q: What is the inventory status for each part? A: TPS77012DBVR (Last Time Buy): 4,300 pcs; TPS77001DBVR (Active): 16,295 pcs; TPS77012DBVT (Obsolete): 2,140 pcs. For new projects, TPS77001DBVR offers the most reliable long-term supply.
