TPS70930DBVR Equivalent & Substitute Parts

Part Overview

The TPS70930DBVR is a linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) component. It delivers a fixed 3V output at 150mA with a maximum input voltage of 30V and a dropout voltage of 1.4V at full load. The device operates across the industrial temperature range of -40°C to 125°C and includes integrated protection features for over-current, over-temperature, reverse-current, and under-voltage lockout conditions. With active product status and ROHS3 compliance, the TPS70930DBVR is suitable for applications requiring low-dropout linear regulation in space-constrained surface-mount designs. Equivalent and substitute parts are identified when electrical performance parameters and mechanical compatibility align with the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS70930DBVR is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Fixed output voltage of 3V
• Output current rating of 150mA
• Maximum input voltage of 30V
• Operating temperature range of -40°C to 125°C
• Surface-mount package compatibility (SOT-23-5 or equivalent pinout)
• Active product status
• ROHS3 compliance

Parametric Equivalents (TPS70930DBVT, TPS709A30DBVT) meet all primary criteria with identical electrical specifications and package footprints, differing only in packaging format (Cut Tape vs. Tape & Reel).

Manufacturer-Recommended Substitute (AP7383-30W5-7) meets all primary criteria with minor variations in quiescent current (3 µA vs. 2.05 µA) and dropout voltage (1.5V vs. 1.4V @ 150mA), which remain within acceptable tolerance for most applications requiring 3V regulation at 150mA.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment with the original TPS70930DBVR.

TPS70930DBVT is a direct parametric equivalent with identical electrical specifications. The only distinction is packaging format (Cut Tape vs. Digi-Reel). This part is suitable for applications where the original packaging format is not a constraint.

TPS709A30DBVT is a parametric equivalent from the same manufacturer with identical electrical performance. It differs in packaging format (Tape & Reel) and base product number designation (TPS709 vs. TPS70930). This part is suitable for high-volume production environments utilizing standard reel-based assembly processes.

AP7383-30W5-7 is a manufacturer-recommended substitute from Diodes Incorporated. It exhibits marginally higher quiescent current (3 µA vs. 2.05 µA) and dropout voltage (1.5V vs. 1.4V @ 150mA). These differences are negligible for most 3V/150mA regulation applications. The part is packaged in SOT-25, which maintains the same footprint class as SOT-23-5. This option is suitable when Texas Instruments parts are unavailable or when supply chain diversification is required.

Frequently Asked Questions (FAQ)

Q: Can TPS70930DBVT be used as a direct replacement for TPS70930DBVR?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output voltage, current rating, dropout voltage, and operating temperature range. The difference is packaging format only (Cut Tape & Digi-Reel vs. standard reel format). PCB footprint and pinout are identical.

Q: What is the difference between TPS709A30DBVT and TPS70930DBVT?

A: Both parts are parametric equivalents with identical electrical performance. The TPS709A30DBVT uses a different base product number (TPS709 vs. TPS70930) and is supplied in Tape & Reel format. Electrical specifications, package type, and pinout are identical.

Q: Can AP7383-30W5-7 replace TPS70930DBVR in all applications?

A: AP7383-30W5-7 is a manufacturer-recommended substitute with the same output voltage, current rating, and input voltage specification. The quiescent current is 3 µA (vs. 2.05 µA) and dropout voltage is 1.5V @ 150mA (vs. 1.4V @ 150mA). These differences are acceptable for standard 3V regulation applications. However, applications with strict power-budget constraints or requiring minimum dropout voltage may require evaluation of the specific design margins.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original TPS70930DBVR specification.

Q: What is the difference between SOT-23-5 and SOT-25 packages?

A: Both are surface-mount packages with identical pinout and footprint class. SOT-25 is a variant designation used by some manufacturers. The physical dimensions and lead spacing are compatible for PCB assembly purposes.

Q: Which substitute part should I select for high-volume production?

A: TPS709A30DBVT is optimized for high-volume production, supplied in standard Tape & Reel format. It offers identical electrical performance and is compatible with automated assembly processes.

Q: Are there inventory considerations when selecting a substitute?

A: Yes. Inventory levels vary by part and supplier. TPS70930DBVR has 36,145 units in stock, TPS70930DBVT has 1,740 units, TPS709A30DBVT has 1,236 units, and AP7383-30W5-7 has 3,985 units. Availability should be confirmed with your supplier for production timelines.
