TPS73213DBVR Equivalent & Substitute Parts

Part Overview

The TPS73213DBVR is a linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) component. It delivers a fixed positive output of 1.3V at 250mA with a maximum dropout voltage of 0.15V, housed in a SOT-23-5 surface mount package. The device is currently in Last Time Buy status, indicating limited availability. Finding equivalent and substitute parts is necessary to ensure design continuity and maintain supply chain flexibility for applications requiring fixed 1.3V regulation with the specified performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS73213DBVR are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Output voltage configuration (Positive, Fixed)
• Output voltage level (1.3V fixed output)
• Current capacity (250mA minimum)
• Maximum input voltage (5.5V or higher)
• Dropout voltage performance (0.15V or lower at rated current)
• Package compatibility (SOT-23-5)
• Surface mount mounting type
• Operating temperature range (-40°C ~ 125°C)

Substitute Categories:

Parametric Equivalent: TPS73213DBVT matches all electrical specifications and output characteristics of the main part. The difference is packaging format (Tape & Reel vs. Cut Tape) and product status (Obsolete vs. Last Time Buy).

Manufacturer Recommended Substitute: TPS78401DBVR is a Texas Instruments linear regulator with adjustable output voltage (1.2V to 5.5V range), higher current capacity (300mA), and improved quiescent current (35µA vs. 550µA). While output type differs (Adjustable vs. Fixed), it can be configured to deliver 1.3V output and provides superior performance characteristics. Packaging is Cut Tape & Digi-Reel format.

Parameter Comparison

Engineering Selection Recommendations

TPS73213DBVT (Parametric Equivalent): This part is electrically and mechanically identical to the TPS73213DBVR, differing only in packaging format (Tape & Reel). However, its Obsolete product status limits its viability for new designs or long-term supply assurance. Selection is appropriate only when existing inventory is available and immediate supply is not a constraint.

TPS78401DBVR (Manufacturer Recommended Substitute): This part is the primary recommended substitute for new designs and ongoing production. It maintains ROHS3 compliance and operates within the required temperature range. The adjustable output configuration requires external resistor network design to set the output voltage to 1.3V, but this is a standard engineering practice. The higher current capacity (300mA vs. 250mA) and significantly lower quiescent current (35µA vs. 550µA) provide performance advantages. The Active product status ensures long-term availability. The higher dropout voltage (0.3V vs. 0.15V) must be evaluated against specific application power budget requirements.

Frequently Asked Questions (FAQ)

Q: Can TPS78401DBVR directly replace TPS73213DBVR without circuit modifications?

A: No. The TPS78401DBVR is an adjustable regulator and requires external resistor divider network to set output voltage to 1.3V. The TPS73213DBVR is a fixed-output device requiring no external components. Pin-compatible replacement is not possible without schematic redesign.

Q: What is the difference between TPS73213DBVR and TPS73213DBVT?

A: Both parts are electrically identical with matching specifications. The difference is packaging format: DBVR uses Tape & Reel (TR) packaging, while DBVT also uses Tape & Reel but carries Obsolete product status. For equivalent functionality, either part performs identically in the circuit.

Q: Is TPS78401DBVR suitable for battery-powered applications?

A: The TPS78401DBVR's quiescent current of 35µA is significantly lower than the TPS73213DBVR's 550µA, making it superior for battery-powered designs. However, the higher dropout voltage (0.3V vs. 0.15V) must be considered when calculating minimum input voltage requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three parts (TPS73213DBVR, TPS73213DBVT, and TPS78401DBVR) are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements.

Q: What is the MSL (Moisture Sensitivity Level) difference between parts?

A: TPS73213DBVR and TPS73213DBVT have MSL 1 (Unlimited shelf life). TPS78401DBVR has MSL 2 (1 Year shelf life), requiring controlled storage conditions. This affects component handling and storage protocols.

Q: Can I use TPS78401DBVR in a fixed 1.3V application without external components?

A: No. The TPS78401DBVR requires external resistor network to establish the output voltage. Using it without proper voltage divider configuration will result in unpredictable output voltage. Refer to the TPS78401 datasheet for resistor selection guidance.
