TLV75719PDRVR Equivalent & Substitute Parts

Part Overview

The TLV75719PDRVR is a linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) device. It delivers a fixed positive output of 1.9V at 1A with a maximum dropout voltage of 0.8V. The device is actively produced and widely stocked (3742 pcs available), making it suitable for applications requiring low-voltage regulation with integrated protection features including current limiting, thermal shutdown, and under-voltage lockout (UVLO).

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter tolerances, accounting for differences in output current capacity, package form factor, and operating temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLV75719PDRVR is determined by the following critical parameters:

• Output voltage matching or functional equivalence within application tolerance
• Input voltage range compatibility (maximum 5.5V)
• Output current capacity sufficient for the application load
• Positive fixed output configuration
• Active product status and current manufacturing availability
• RoHS3 compliance for regulatory alignment
• Protection feature set (current limiting and thermal management)

The RT9166-12GVL is identified as a substitute option. However, this part exhibits a lower fixed output voltage (1.2V versus 1.9V) and reduced output current capacity (300mA versus 1A). These differences require application-level evaluation to determine functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the TLV75719PDRVR and RT9166-12GVL maintain active product status with ROHS3 compliance and current manufacturing availability. Selection between these devices depends on application-specific requirements:

The TLV75719PDRVR is the primary choice for applications requiring 1.9V output at 1A with extended operating temperature range (-40°C to 125°C junction temperature). The 6-WDFN package with exposed pad provides thermal management suitable for higher current delivery.

The RT9166-12GVL is applicable only in applications where the lower 1.2V output voltage and reduced 300mA current capacity align with circuit requirements. The SOT-23-3 package offers space-constrained design alternatives. The narrower operating temperature range (-40°C to 85°C ambient) must be evaluated against thermal environment specifications.

Frequently Asked Questions (FAQ)

Q: Can the RT9166-12GVL directly replace the TLV75719PDRVR?

A: Direct replacement is not possible. The RT9166-12GVL provides a different fixed output voltage (1.2V versus 1.9V) and lower output current (300mA versus 1A). Substitution requires circuit redesign to accommodate these electrical differences.

Q: What are the key differences in package form factor?

A: The TLV75719PDRVR uses a 6-WDFN package with exposed pad, optimized for surface mount assembly with thermal dissipation. The RT9166-12GVL uses a SOT-23-3 package, a smaller form factor suitable for space-constrained applications but with reduced thermal capability.

Q: Are both parts RoHS compliant?

A: Yes. Both the TLV75719PDRVR and RT9166-12GVL are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the significance of the operating temperature range difference?

A: The TLV75719PDRVR operates to 125°C junction temperature, while the RT9166-12GVL operates to 85°C ambient temperature. Applications requiring operation in elevated thermal environments must account for this specification difference.

Q: How do the protection features compare?

A: Both devices include over-current and over-temperature protection. The TLV75719PDRVR additionally includes under-voltage lockout (UVLO), providing enhanced input supply monitoring. Both offer current limiting and thermal shutdown functions.
