TLV70130DBVR Equivalent & Substitute Parts

Part Overview

The TLV70130DBVR 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 dropout voltage of 0.4V at 50mA, housed in an SOT-23-5 surface mount package. The device is currently in active production status with 3383 units available in cut tape packaging. This regulator is designed for low-power applications requiring stable 3V rails with minimal quiescent current draw of 4.5µA and integrated over-current and reverse polarity protection.

Equivalent substitute parts are necessary when specific packaging formats (tape & reel versus cut tape) are required for manufacturing processes, or when alternative dropout voltage characteristics better suit application requirements while maintaining core electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLV70130DBVR is determined by the following criteria:

Electrical Parameters (Must Match):

• Output voltage: 3V fixed
• Output current capability: 150mA
• Input voltage rating: 24V maximum
• Quiescent current: 4.5µA
• PSRR: 60dB at 100kHz
• Protection features: Over current and reverse polarity protection
• Operating temperature range: -40°C to 125°C

Mechanical Parameters (Must Match):

• Package type: SOT-23-5 (SC-74A)
• Mounting type: Surface mount

Variable Parameters (Allowed to Differ):

• Packaging format: Cut tape (CT), tape & reel (TR), or Digi-Reel®
• Dropout voltage specification: Acceptable variance based on application requirements

The TLV70130DBVT and TLV70430 series variants meet these substitution criteria while offering different packaging options and dropout voltage characteristics.

Parameter Comparison

Engineering Selection Recommendations

All four parts maintain active production status and full ROHS3 compliance, ensuring long-term availability and regulatory conformance for production designs.

TLV70130DBVT is a direct parametric equivalent to the TLV70130DBVR, differing only in packaging format (tape & reel versus cut tape). Selection between these two depends on assembly line requirements and tape reel compatibility with pick-and-place equipment.

TLV70430DBVR and TLV70430DBVT are functionally equivalent alternatives with a higher dropout voltage specification of 1.1V at 100mA compared to 0.4V at 50mA for the TLV70130 series. These variants are suitable for applications where the increased dropout voltage does not compromise system performance. The TLV70430 series offers significantly higher inventory availability (65400 units for the cut tape variant), which may provide supply chain advantages.

Selection between TLV70130 and TLV70430 variants should be based on the specific input voltage margin and thermal dissipation requirements of the target application. Both series deliver identical output voltage, current capacity, quiescent current, and protection features.

Frequently Asked Questions (FAQ)

Q: Can TLV70430DBVR replace TLV70130DBVR in my design?

A: Yes, provided your application tolerates the higher dropout voltage of 1.1V at 100mA versus 0.4V at 50mA. Both parts deliver 3V at 150mA with identical quiescent current, PSRR, and protection features. Verify that your input voltage margin accommodates the increased dropout specification.

Q: What is the difference between cut tape (CT) and tape & reel (TR) packaging?

A: Cut tape packaging supplies individual components on carrier tape suitable for manual handling or small-scale assembly. Tape & reel packaging winds the carrier tape on a reel for automated pick-and-place equipment in high-volume manufacturing. Electrical and mechanical specifications are identical; selection depends on assembly process requirements.

Q: Are all four parts pin-compatible?

A: Yes. All variants use the SOT-23-5 package with identical pinout and electrical interface. PCB layout and schematic connections require no modification when substituting between these parts.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All four parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is 1 (unlimited) for all variants, indicating no special storage or handling requirements.

Q: Which part should I select for new designs?

A: For new designs, select based on packaging format compatibility with your assembly process and dropout voltage requirements. The TLV70130 series with 0.4V dropout is preferred when input voltage margin is limited. The TLV70430 series with higher inventory availability may offer supply chain benefits for high-volume production.
