TLV75728PDRVR Equivalent & Substitute Parts

Part Overview

The TLV75728PDRVR is a linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) device. It delivers a fixed positive output of 2.8V at 1A with a maximum dropout voltage of 0.65V. The device is housed in a 6-WSON (2x2) package and is currently in active production status. Finding equivalent or substitute parts may be necessary due to supply constraints, design optimization requirements, or application-specific performance needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV75728PDRVR is determined by the following critical parameters:

• Output voltage specification (2.8V fixed)
• Output current capability (1A minimum)
• Maximum input voltage tolerance (5.5V)
• Dropout voltage performance (0.65V @ 1A or better)
• Package compatibility (6-WSON or equivalent footprint)
• Operating temperature range (-40°C to 125°C or wider)
• RoHS3 compliance and active product status

The substitute part RT9166-12GVL does not meet the primary substitution criteria for the TLV75728PDRVR. The RT9166-12GVL is specified for 1.2V output at 300mA maximum current, which differs significantly from the 2.8V, 1A requirements of the main part. Additionally, the RT9166-12GVL uses a SOT-23-3L package, which is not mechanically compatible with the 6-WSON footprint. This part represents a different voltage and current class and should not be considered a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Based on the provided specifications, the RT9166-12GVL is not a suitable substitute for the TLV75728PDRVR. The critical incompatibilities are:

• Output voltage mismatch (1.2V vs. 2.8V)
• Output current insufficiency (300mA vs. 1A requirement)
• Package footprint incompatibility (SOT-23-3L vs. 6-WSON)
• Operating temperature range limitation (85°C max vs. 125°C requirement)

Both devices maintain active product status and RoHS3 compliance. However, these compliance attributes alone do not establish substitutability when fundamental electrical and mechanical parameters diverge.

For applications requiring the TLV75728PDRVR specifications, direct replacement with this part number or identification of alternative regulators with matching 2.8V output, 1A current capability, and 6-WSON packaging is necessary.

Frequently Asked Questions (FAQ)

Q: Can the RT9166-12GVL replace the TLV75728PDRVR in my design?

A: No. The RT9166-12GVL is specified for 1.2V output at 300mA, while the TLV75728PDRVR provides 2.8V at 1A. These are different voltage and current classes. Additionally, the package types are incompatible.

Q: What makes two linear regulators substitutable?

A: Substitutability requires matching or exceeding output voltage, output current capability, input voltage tolerance, dropout voltage performance, package footprint compatibility, and operating temperature range. The TLV75728PDRVR and RT9166-12GVL do not meet these criteria.

Q: Are both parts RoHS compliant?

A: Yes, both the TLV75728PDRVR and RT9166-12GVL are ROHS3 compliant. However, compliance certification alone does not establish electrical or mechanical compatibility.

Q: What is the significance of the 6-WSON package for the TLV75728PDRVR?

A: The 6-WSON (2x2) package defines the physical footprint and pin configuration. Substitute parts must use the same or compatible package to ensure PCB layout compatibility without redesign.

Q: Why is the operating temperature range important for substitution?

A: The TLV75728PDRVR operates to 125°C (junction temperature), while the RT9166-12GVL is limited to 85°C (ambient temperature). Applications requiring the full temperature range of the main part cannot use the substitute.
