TPS72116DBVR Equivalent & Substitute Parts

Part Overview

The TPS72116DBVR is a linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) device. It delivers a fixed positive output of 1.6V at 150mA with a maximum input voltage of 5.5V and a dropout voltage of 0.24V at full load. The device operates across the industrial temperature range of -40°C to 125°C and includes integrated protection features for overcurrent, overtemperature, and reverse polarity conditions. With an active product status and ROHS3 compliance, the TPS72116DBVR is suitable for applications requiring low-voltage regulation in space-constrained surface-mount designs. Equivalent and substitute parts are identified when design requirements change, inventory constraints occur, or alternative sourcing becomes necessary while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the TPS72116DBVR are categorized based on strict electrical and mechanical compatibility criteria:

Parametric Equivalent (Direct Replacement): Parts that match all critical electrical parameters including output voltage (1.6V), output current (150mA), input voltage rating (5.5V), package type (SOT-23-5), and operating temperature range (-40°C to 125°C). These parts are interchangeable without circuit modification.

Manufacturer Recommended Alternatives: Parts that share the same output current (150mA), package type (SOT-23-5), and mounting configuration but may differ in output voltage, input voltage rating, quiescent current, or operating temperature range. Selection requires verification that the alternative output voltage and electrical characteristics are compatible with the target application.

The key parameters determining substitution eligibility are:

• Output current capacity (150mA)
• Package type (SOT-23-5)
• Surface mount configuration
• Mounting type compatibility
• RoHS3 compliance status

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Parametric Equivalent): TPS72116DBVT is a parametric equivalent to TPS72116DBVR. Both devices are manufactured by Texas Instruments with identical electrical specifications, output voltage (1.6V), current rating (150mA), input voltage maximum (5.5V), dropout voltage (0.24V @ 150mA), and operating temperature range (-40°C to 125°C). The primary difference is packaging format (Cut Tape & Digi-Reel versus standard packaging). Both maintain ROHS3 compliance and are suitable for direct substitution in existing designs.

Alternative with Matching Output Voltage: S-13R1A16-M5T1U3 from ABLIC Inc. provides the same 1.6V output voltage and 150mA current capacity in SOT-23-5 package. This part is suitable for applications where the 1.6V output is critical. However, the operating temperature range is limited to -40°C to 85°C (versus 125°C maximum for the TPS72116DBVR), and dropout voltage is higher at 0.48V @ 100mA. Selection requires confirmation that the reduced temperature range and higher dropout voltage are acceptable for the target application.

Alternatives with Different Output Voltage: ADP121-AUJZ25R7, MAX8885EUK25+T, and MCP1711T-25I/OT all provide 2.5V output voltage instead of 1.6V. These parts are suitable only for applications where 2.5V regulation is required. All three maintain 150mA output current and SOT-23-5 package compatibility. Selection among these alternatives depends on specific requirements for quiescent current, dropout voltage, and operating temperature range. ADP121-AUJZ25R7 supports the full -40°C to 125°C temperature range, while MAX8885EUK25+T and MCP1711T-25I/OT are limited to -40°C to 85°C.

All substitute parts listed maintain ROHS3 compliance and are classified as active products with current manufacturing status.

Frequently Asked Questions (FAQ)

Q: Can TPS72116DBVT be used as a direct replacement for TPS72116DBVR? A: Yes. TPS72116DBVT is a parametric equivalent with identical electrical specifications, output voltage, current rating, and operating temperature range. The difference is packaging format (tape and reel configuration). Both parts are suitable for direct substitution in existing designs without circuit modification.

Q: What is the difference between the 1.6V and 2.5V output alternatives? A: The TPS72116DBVR and S-13R1A16-M5T1U3 provide 1.6V fixed output, while ADP121-AUJZ25R7, MAX8885EUK25+T, and MCP1711T-25I/OT provide 2.5V fixed output. Output voltage selection is application-specific and cannot be changed without circuit redesign. Parts with different output voltages are not interchangeable.

Q: Can I use a 2.5V regulator in place of the 1.6V TPS72116DBVR? A: No. The output voltage is a fixed characteristic determined by the regulator design. Using a 2.5V regulator in a circuit designed for 1.6V will result in incorrect voltage delivery to downstream components and potential circuit malfunction.

Q: What are the key differences between S-13R1A16-M5T1U3 and TPS72116DBVR? A: Both provide 1.6V output at 150mA in SOT-23-5 package. Key differences are: S-13R1A16-M5T1U3 has a maximum operating temperature of 85°C (versus 125°C), higher dropout voltage of 0.48V @ 100mA (versus 0.24V @ 150mA), and significantly lower quiescent current of 1 µA (versus 120 µA). Selection depends on whether the reduced temperature range and higher dropout voltage are acceptable for the application.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All parts listed in this reference maintain ROHS3 compliance status, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: What is the significance of the SOT-23-5 package specification? A: SOT-23-5 is a surface-mount package with five leads in a small outline configuration. All parts listed use this package type or compatible variants (TSOT-23-5), ensuring mechanical and electrical compatibility with existing PCB layouts and soldering processes.

Q: Which substitute part has the lowest quiescent current? A: S-13R1A16-M5T1U3 and MCP1711T-25I/OT both have very low quiescent currents of 1 µA and 1.27 µA respectively, compared to 120 µA for the TPS72116DBVR. These alternatives are suitable for battery-powered or ultra-low-power applications where quiescent current is a critical design parameter.

Q: Can I use MAX8885EUK25+T if my application requires operation above 85°C? A: No. MAX8885EUK25+T is rated for operation only to 85°C maximum. For applications requiring operation to 125°C, use TPS72116DBVR, TPS72116DBVT, or ADP121-AUJZ25R7 (if 2.5V output is acceptable).
