TPS70625DBVR Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The TPS70625DBVR is an active linear voltage regulator manufactured by Texas Instruments, classified as a Power Management IC (PMIC). This device functions as a positive fixed output voltage regulator delivering 150mA output current at 2.5V. The part is in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or when alternative manufacturers' components meet the same electrical and mechanical specifications within the allowed parameter ranges for this product category.

Substitute Part Grouping Explanation

Substitute parts for the TPS70625DBVR are classified into two categories based on parametric equivalence:

Parametric Equivalent (Direct Substitute): TPS70625DBVT matches all critical electrical and mechanical parameters with the main part. Both devices share identical output voltage (2.5V), output current (150mA), maximum input voltage (6.5V), package type (SOT-23-5), operating temperature range (-40°C to 125°C), and protection features. The only difference is packaging format (Tape & Reel for both). This part is a direct functional equivalent suitable for one-to-one replacement.

Manufacturer Recommended Equivalent: NCP699SN33T1G is a onsemi alternative that differs in output voltage specification (3.3V versus 2.5V) and certain electrical characteristics. This part is included as a manufacturer-recommended option where circuit design permits the higher output voltage and can accommodate the different quiescent current (90 µA versus 2.55 µA) and PSRR specifications.

Substitution eligibility is determined by the following parameters:

• Output voltage compatibility
• Output current rating (minimum 150mA required)
• Maximum input voltage (minimum 6.5V required)
• Package type (SOT-23-5 required)
• Operating temperature range coverage
• Protection feature set
• RoHS3 compliance status

Parameter Comparison

Engineering Selection Recommendations

TPS70625DBVT is the preferred substitute when direct replacement is required. This part maintains identical electrical specifications and operating characteristics as the TPS70625DBVR. Both devices are active products with ROHS3 compliance and unlimited moisture sensitivity rating. Selection of TPS70625DBVT introduces no design risk when the original part becomes unavailable.

NCP699SN33T1G is suitable only when circuit design specifications permit a 3.3V output voltage instead of 2.5V. This onsemi alternative is recommended by the manufacturer but requires design verification due to the following differences: reduced maximum input voltage (6V versus 6.5V), significantly higher quiescent current consumption (90 µA versus 2.55 µA), lower maximum operating temperature (85°C versus 125°C), and reduced protection feature set (lacks Reverse Polarity and UVLO protection). This part is appropriate for applications where the output voltage differential and operational constraints are acceptable.

All three parts maintain active product status and full RoHS3 compliance, ensuring long-term availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can TPS70625DBVT be used as a direct replacement for TPS70625DBVR?

A: Yes. TPS70625DBVT is a parametric equivalent with identical output voltage (2.5V), output current (150mA), input voltage rating (6.5V maximum), operating temperature range (-40°C to 125°C), package type (SOT-23-5), and protection features. No circuit modifications are required.

Q: What are the key differences between TPS70625DBVR and NCP699SN33T1G?

A: The primary differences are output voltage (2.5V versus 3.3V), quiescent current (2.55 µA versus 90 µA), maximum input voltage (6.5V versus 6V), maximum operating temperature (125°C versus 85°C), and protection features. NCP699SN33T1G lacks Reverse Polarity and UVLO protection present in the TPS70625DBVR.

Q: Is NCP699SN33T1G compatible with designs requiring 2.5V output?

A: No. NCP699SN33T1G is fixed at 3.3V output and cannot be configured for 2.5V operation. This part is suitable only for applications designed for 3.3V output voltage.

Q: Are all three parts available in the same package?

A: TPS70625DBVR and TPS70625DBVT are both available in SOT-23-5 (SC-74A) package. NCP699SN33T1G is available in 5-TSOP (SOT-23-5 Thin) package, which is mechanically compatible but represents a thin variant of the standard SOT-23-5 footprint.

Q: What is the temperature operating range difference between these parts?

A: TPS70625DBVR and TPS70625DBVT both operate from -40°C to 125°C. NCP699SN33T1G operates from -40°C to 85°C, providing a narrower high-temperature range. Applications requiring operation above 85°C must use the Texas Instruments parts.

Q: Do all parts meet RoHS3 compliance?

A: Yes. TPS70625DBVR, TPS70625DBVT, and NCP699SN33T1G are all ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).
