TLV75712PDBVR Equivalent & Substitute Parts

Part Overview

The TLV75712PDBVR is a linear voltage regulator IC manufactured by Texas Instruments, designed for positive fixed output applications. This device delivers 1A output current at a fixed 1.2V output voltage and operates across an industrial temperature range of -40°C to 125°C. The regulator is housed in a SOT-23-5 surface mount package and includes integrated protection features including current limiting, thermal shutdown, and under-voltage lockout (UVLO). The product maintains active status with extensive inventory availability, making it suitable for production applications requiring reliable voltage regulation in compact form factors.

Equivalent and substitute parts are identified based on matching critical electrical parameters: fixed 1.2V output voltage, positive output configuration, surface mount packaging compatibility, and active product status with equivalent protection features and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLV75712PDBVR are identified based on the following critical substitution criteria:

Primary Matching Parameters:

• Fixed output voltage of 1.2V
• Positive output configuration
• Surface mount packaging (SOT-23 family)
• Active product status
• ROHS3 compliance
• Over-current and thermal protection features

Acceptable Variation Parameters:

• Output current capacity (minimum 300mA required for functional equivalence)
• Voltage dropout specifications (lower values indicate improved performance)
• Quiescent current specifications
• Operating temperature range (minimum -40°C to 85°C acceptable)
• Package variants within SOT-23 family (SOT-23-3L, SOT-23-5)

The RT9166-12GVL qualifies as a substitute based on matching the fixed 1.2V output voltage, positive output configuration, surface mount technology, active status, and equivalent protection architecture. While output current capacity differs (300mA versus 1A), this represents a functional limitation rather than incompatibility for applications within the 300mA current envelope.

Engineering Selection Recommendations

TLV75712PDBVR Selection Criteria: Select the TLV75712PDBVR for applications requiring 1A output current capacity, extended junction temperature operation to 125°C, and integrated UVLO protection. This device maintains active product status with ROHS3 compliance and REACH unaffected designation, suitable for production deployment.

RT9166-12GVL Selection Criteria: The RT9166-12GVL serves as a substitute for applications with output current requirements not exceeding 300mA. This device provides superior voltage dropout performance (0.23V typical at 300mA versus 1.1V at 1A for the primary part) and maintains active product status with equivalent ROHS3 compliance and REACH unaffected designation. Operating temperature range extends to 85°C ambient, suitable for standard industrial applications.

Compliance Basis: Both devices maintain active product status, ROHS3 compliance, and REACH unaffected designation. Selection between these parts depends solely on output current capacity requirements and operating temperature envelope specifications.

Frequently Asked Questions (FAQ)

Q: Can the RT9166-12GVL directly replace the TLV75712PDBVR in all applications?

A: The RT9166-12GVL functions as a substitute only for applications where output current does not exceed 300mA. The TLV75712PDBVR supports 1A output current; applications requiring higher current must use the primary part or equivalent 1A-rated alternatives.

Q: What are the package compatibility considerations?

A: The TLV75712PDBVR uses SOT-23-5 packaging (5-pin), while the RT9166-12GVL uses SOT-23-3L packaging (3-pin). PCB layout modifications are required for substitution due to different pin counts and configurations. Pin function mapping must be verified before implementation.

Q: How do voltage dropout specifications affect substitution?

A: The RT9166-12GVL exhibits lower voltage dropout (0.23V typical at 300mA) compared to the TLV75712PDBVR (1.1V at 1A). For applications with tight input voltage margins, the RT9166-12GVL provides improved performance. For applications with adequate input voltage headroom, both devices function equivalently.

Q: Are there temperature range limitations for substitution?

A: The TLV75712PDBVR operates to 125°C junction temperature, while the RT9166-12GVL operates to 85°C ambient temperature. Applications requiring operation above 85°C ambient or 125°C junction temperature must use the TLV75712PDBVR.

Q: Do both devices provide equivalent protection features?

A: Both devices include over-current and thermal protection. The TLV75712PDBVR additionally integrates UVLO (under-voltage lockout) protection. Applications requiring UVLO functionality must use the TLV75712PDBVR.

Q: What is the basis for these substitution relationships?

A: Substitution is based on matching fixed 1.2V output voltage, positive output configuration, surface mount technology, active product status, and ROHS3 compliance. Output current capacity and operating temperature represent acceptable variation parameters within the substitution framework.
