TPS70615DRVR Equivalent & Substitute Parts

Part Overview

The TPS70615DRVR is a linear voltage regulator IC from Texas Instruments designed for positive fixed output applications. It delivers 150mA output current at a fixed 1.5V output voltage with a maximum input voltage of 6.5V. The device is housed in a 6-WSON (2x2) package with an exposed pad and includes integrated protection features for over-current, over-temperature, reverse polarity, and under-voltage lockout conditions. The TPS70615DRVR is classified as an active product and is ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter set.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS70615DRVR are identified based on strict equivalence across the following critical parameters:

• Fixed output voltage of 1.5V
• Output current capability of 150mA
• Maximum input voltage of 6.5V
• Positive output configuration with single regulator
• 6-WSON (2x2) package with exposed pad
• Surface mount technology
• Operating temperature range of -40°C to 125°C
• Integrated protection features (Over Current, Over Temperature, Reverse Polarity, UVLO)
• ROHS3 compliance

Two substitute parts meet these criteria: TPS70615DRVT and TPS71715QDRVRQ1. Both maintain identical electrical specifications for output voltage, output current, input voltage rating, and package configuration. The TPS70615DRVT differs only in packaging format (Tape & Reel versus bulk). The TPS71715QDRVRQ1 is an automotive-grade variant with AEC-Q100 qualification and includes enhanced specifications in quiescent current and supply current parameters.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TPS70615DRVR, TPS70615DRVT, and TPS71715QDRVRQ1—are active products with ROHS3 compliance and identical core electrical specifications for output voltage, output current, and input voltage rating.

The TPS70615DRVT is a direct parametric equivalent to the TPS70615DRVR, differing only in packaging format (Tape & Reel). Selection between these two depends on procurement and assembly requirements rather than electrical performance.

The TPS71715QDRVRQ1 is an automotive-grade variant with AEC-Q100 qualification. This part is suitable for applications requiring automotive-level reliability and qualification. The TPS71715QDRVRQ1 exhibits lower quiescent current (80 µA versus 2.55 µA) and lower maximum supply current (100 µA versus 350 µA), along with a specified dropout voltage of 0.3V at 150mA. These differences reflect automotive-grade design optimization and do not preclude substitution in standard industrial applications where the enhanced specifications provide additional margin.

Frequently Asked Questions (FAQ)

Q: Can TPS70615DRVT be used as a direct replacement for TPS70615DRVR?

A: Yes. The TPS70615DRVT is a parametric equivalent with identical electrical specifications. The only difference is packaging format: TPS70615DRVR is supplied in bulk, while TPS70615DRVT is supplied in Tape & Reel format. Both are suitable for the same circuit applications.

Q: Is TPS71715QDRVRQ1 compatible with designs specified for TPS70615DRVR?

A: Yes. The TPS71715QDRVRQ1 maintains the same output voltage (1.5V), output current (150mA), input voltage rating (6.5V), and package configuration (6-WSON 2x2). The automotive-grade qualification and enhanced specifications (lower quiescent current, specified dropout voltage) make it suitable for substitution. Applications not requiring automotive qualification can use this part without circuit modification.

Q: What is the significance of the AEC-Q100 qualification on TPS71715QDRVRQ1?

A: AEC-Q100 qualification indicates the part meets automotive industry reliability and quality standards. This qualification is relevant for automotive applications but does not restrict use in non-automotive applications. The part is suitable for any application where the electrical specifications are met.

Q: Are all three parts available in the same package?

A: Yes. All three parts use the 6-WDFN Exposed Pad package (6-WSON 2x2 supplier designation). PCB layout and footprint are identical across all three parts.

Q: What is the difference in quiescent current between TPS70615DRVR and TPS71715QDRVRQ1?

A: The TPS70615DRVR has a quiescent current of 2.55 µA, while the TPS71715QDRVRQ1 has a quiescent current of 80 µA. This difference reflects automotive-grade design optimization. For battery-powered or ultra-low-power applications where quiescent current is critical, the TPS70615DRVR or TPS70615DRVT should be selected.

Q: Can these parts be used interchangeably in production?

A: TPS70615DRVR and TPS70615DRVT can be used interchangeably from an electrical standpoint. TPS71715QDRVRQ1 can also be used interchangeably if the application does not have specific quiescent current or supply current constraints. Verify component availability and procurement lead times when selecting between these options.
