TLV75709PDRVR Equivalent & Substitute Parts

Part Overview

The TLV75709PDRVR is a linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) component. It delivers a fixed positive output of 0.9V at 1A with a maximum dropout voltage of 1.35V @ 1A. The device is housed in a 6-WSON (2x2) package and is designed for surface mount applications. This regulator includes integrated protection features including current limit, thermal shutdown, and UVLO (Under-Voltage Lock-Out), along with an enable control feature. The product maintains Active status and is RoHS3 compliant with MSL Level 1 (Unlimited moisture sensitivity). Finding equivalent or substitute parts may be necessary due to inventory constraints, lead time requirements, or specific application design flexibility within compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLV75709PDRVR are identified based on the following critical parameters that determine functional compatibility:

Output Voltage Compatibility: The substitute part RT9166-12GVL operates at a fixed output voltage of 1.2V, which differs from the main part's 0.9V specification. This represents a different voltage class and limits direct substitution to applications where the 1.2V output is acceptable within the circuit design.

Output Current Rating: The RT9166-12GVL provides 300mA maximum output current, compared to the TLV75709PDRVR's 1A rating. This reduced current capability restricts the substitute to lower-power applications.

Input Voltage Range: Both parts accept a maximum input voltage of 5.5V, maintaining compatibility in this parameter.

Package and Mounting: The substitute uses a SOT-23-3L package (TO-236-3), which differs from the 6-WSON (2x2) package of the main part. This requires PCB layout redesign and is not a pin-compatible substitution.

Operating Temperature Range: The substitute operates from -40°C to 85°C (TA), which is narrower than the main part's -40°C to 125°C (TJ) range.

Protection and Control Features: The substitute includes Over Current and Over Temperature protection but lacks the UVLO feature and Enable control present in the main part.

Substitution is only valid when the application requirements align with the reduced current rating, different output voltage, narrower temperature range, and alternative package footprint.

Parameter Comparison

Engineering Selection Recommendations

Both the TLV75709PDRVR and RT9166-12GVL maintain Active product status and are RoHS3 compliant, confirming ongoing manufacturer support and environmental regulation adherence. The RT9166-12GVL is not a direct pin-compatible or functional equivalent due to differences in output voltage class, current rating, and package footprint.

Selection of the RT9166-12GVL as a substitute requires verification that the application circuit can operate at 1.2V instead of 0.9V, that the maximum load current does not exceed 300mA, and that the PCB layout can accommodate the SOT-23-3L package. The narrower operating temperature range (-40°C to 85°C) must also be confirmed as acceptable for the intended deployment environment.

Frequently Asked Questions (FAQ)

Q: Can the RT9166-12GVL directly replace the TLV75709PDRVR on the same PCB?

A: No. The RT9166-12GVL uses a SOT-23-3L package, while the TLV75709PDRVR uses a 6-WSON (2x2) package. These are not pin-compatible, and PCB layout redesign is required.

Q: What is the primary limitation when using RT9166-12GVL as a substitute?

A: The output current is limited to 300mA compared to the main part's 1A rating. Applications requiring higher current delivery cannot use this substitute.

Q: Does the RT9166-12GVL provide the same output voltage?

A: No. The RT9166-12GVL provides 1.2V fixed output, while the TLV75709PDRVR provides 0.9V. The circuit design must accommodate this voltage difference.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both the TLV75709PDRVR and RT9166-12GVL are RoHS3 compliant and REACH unaffected.

Q: What is the temperature operating range difference?

A: The TLV75709PDRVR operates from -40°C to 125°C (junction temperature), while the RT9166-12GVL operates from -40°C to 85°C (ambient temperature). Applications requiring operation above 85°C ambient cannot use the substitute.

Q: Does the RT9166-12GVL include UVLO protection?

A: No. The RT9166-12GVL includes Over Current and Over Temperature protection but does not include UVLO (Under-Voltage Lock-Out) or Enable control features present in the TLV75709PDRVR.
