TPS76132DBVR Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The TPS76132DBVR is a linear voltage regulator IC manufactured by Texas Instruments, classified as a Power Management (PMIC) component. This device provides a fixed positive output of 3.2V at 100mA in a surface-mount SOT-23-5 package. The part is currently in Last Time Buy status, indicating end-of-life production. Identifying equivalent and substitute parts is necessary to ensure design continuity and maintain supply chain flexibility for applications requiring 3.2V regulated output with 100mA capacity.

Substitute Part Grouping Explanation

Substitute parts for the TPS76132DBVR are classified based on the following substitution criteria:

Parametric Equivalent: Parts that maintain identical or functionally equivalent electrical specifications within the allowed tolerances for the application.

Manufacturer Recommended Substitutes: Parts recommended by manufacturers as direct replacements or upgrades, which may offer enhanced performance or extended availability.

The key parameters determining substitution eligibility are:

• Package type (SOT-23-5 / SC-74A)
• Output voltage configuration (Fixed positive output)
• Output current capability (100mA minimum)
• Maximum input voltage (16V minimum)
• Operating temperature range (-40°C ~ 125°C)
• Surface-mount mounting type
• Compliance certifications (RoHS3, REACH Unaffected)

Parameter Comparison

Engineering Selection Recommendations

TPS76132DBVT (Parametric Equivalent): This part is the direct parametric equivalent to the TPS76132DBVR, differing only in packaging format (Tape & Reel vs. Cut Tape). Both parts maintain identical electrical specifications, output voltage, current capacity, and protection features. The TPS76132DBVT is in Active product status, making it the preferred choice for design continuity. No circuit modifications are required for substitution.

TPS7A2401DBVR (Manufacturer Recommended Upgrade): This Texas Instruments part offers enhanced performance characteristics including adjustable output voltage (1.24V ~ 17.75V), doubled output current capacity (200mA), improved quiescent current (4.5 µA vs. 115 µA), and superior PSRR performance. The adjustable output requires external resistor network configuration to set the 3.2V output. This part is suitable for applications where the additional current capacity and lower quiescent current provide system-level benefits. Circuit redesign is required to implement the adjustable output configuration.

LD2981CM50TR and LD2981ABM50TR (STMicroelectronics Alternatives): These STMicroelectronics parts provide equivalent package, mounting type, and current capacity. However, both parts output a fixed 5V rather than 3.2V. These substitutes are applicable only in applications where the output voltage can be modified to 5V or where a 5V supply is acceptable. Both parts are in Active product status with higher inventory availability. Packaging differs between the two models (Tape & Reel vs. Cut Tape & Digi-Reel).

Frequently Asked Questions (FAQ)

Q: Can I use TPS76132DBVT as a direct replacement for TPS76132DBVR?

A: Yes. The TPS76132DBVT is a parametric equivalent with identical electrical specifications. The only difference is packaging format. Both parts deliver 3.2V at 100mA with the same dropout voltage, quiescent current, and protection features. No circuit modifications are required.

Q: What is the difference between TPS76132DBVR and TPS7A2401DBVR?

A: The TPS7A2401DBVR is an adjustable output regulator with doubled current capacity (200mA vs. 100mA) and significantly lower quiescent current (4.5 µA vs. 115 µA). To use it as a substitute, external resistors must be added to set the output voltage to 3.2V. The TPS76132DBVR provides a fixed 3.2V output without external configuration.

Q: Can I substitute the LD2981 series parts for the TPS76132DBVR?

A: The LD2981CM50TR and LD2981ABM50TR are not direct substitutes because they output 5V instead of 3.2V. These parts are suitable only if your application can operate at 5V or if the output voltage requirement can be modified. Both parts maintain the same package type, current capacity, and operating temperature range.

Q: What packaging formats are available for these regulators?

A: All substitute parts use the SOT-23-5 package (SC-74A, SOT-753). Packaging format variations include Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel. These are supply format differences only and do not affect electrical performance or circuit compatibility.

Q: Are all these parts RoHS3 compliant?

A: Yes. The TPS76132DBVR and all listed substitute parts are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited). All parts are REACH Unaffected and suitable for applications requiring environmental compliance.

Q: Which substitute offers the best performance improvement?

A: The TPS7A2401DBVR provides the most significant performance enhancements: doubled output current (200mA), 96% reduction in quiescent current (4.5 µA), and improved PSRR. However, this requires circuit redesign to implement adjustable output configuration. For drop-in replacement without circuit changes, the TPS76132DBVT is the optimal choice.
