TPS70915DBVR Equivalent & Substitute Parts

Part Overview

The TPS70915DBVR is a linear voltage regulator IC manufactured by Texas Instruments, designed for positive fixed output applications. It delivers 150mA output current at a fixed 1.5V output voltage in a compact SOT-23-5 surface mount package. The device is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or specific application parameters that align with the electrical and mechanical specifications of this regulator family.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS70915DBVR are identified based on strict alignment with the following critical parameters:

• Output voltage fixed at 1.5V
• Output current capability of 150mA
• Positive output configuration
• SOT-23-5 package (SC-74A, SOT-753)
• Surface mount technology
• Operating temperature range -40°C to 125°C
• Active product status
• RoHS3 compliance

Two substitute parts meet these criteria: the TPS70915DBVT (parametric equivalent from Texas Instruments) and the LD39015M15R (manufacturer-recommended alternative from STMicroelectronics). Both devices share identical output specifications and package form factors, enabling direct functional substitution within the specified electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

TPS70915DBVT (Texas Instruments): This part is a parametric equivalent to the TPS70915DBVR with identical electrical specifications and packaging. Selection of this substitute is appropriate when TPS70915DBVR inventory is unavailable. Both parts share the same base product number (TPS70915) and differ only in tape reel configuration. RoHS3 compliance and Active product status are maintained.

LD39015M15R (STMicroelectronics): This part meets the core functional requirements of 1.5V fixed output at 150mA in SOT-23-5 packaging. The maximum input voltage specification is 5.5V compared to 30V for the TPS70915DBVR, and quiescent current is higher at 50µA versus 2.05µA. Selection of this substitute is appropriate only when the application input voltage does not exceed 5.5V and higher quiescent current is acceptable. RoHS3 compliance and Active product status are maintained.

Frequently Asked Questions (FAQ)

Q: Can TPS70915DBVT be used as a direct replacement for TPS70915DBVR?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications, output voltage, output current, and package form factor. The difference is limited to tape reel configuration. Direct substitution is supported.

Q: What are the limitations of using LD39015M15R as a substitute?

A: The LD39015M15R has a maximum input voltage rating of 5.5V, compared to 30V for the TPS70915DBVR. Applications requiring input voltages above 5.5V cannot use this substitute. Additionally, quiescent current is 50µA versus 2.05µA, which may impact low-power standby applications. The package and output specifications remain compatible.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. Both TPS70915DBVT and LD39015M15R are RoHS3 compliant, matching the compliance status of the TPS70915DBVR.

Q: Do substitute parts use the same package?

A: Yes. All three parts use the SC-74A, SOT-753 package (SOT-23-5 supplier designation), enabling identical PCB footprints and assembly processes.

Q: What is the operating temperature range for all parts?

A: All three parts operate across -40°C to 125°C, providing identical thermal performance specifications.
