TPS73001DBVR Equivalent & Substitute Parts

Part Overview

The TPS73001DBVR is an active linear voltage regulator IC from Texas Instruments, classified as a positive adjustable output power management integrated circuit. This device delivers 200mA output current in a compact SOT-23-6 surface mount package and maintains active product status with full RoHS3 compliance. The regulator incorporates integrated protection features including over-current, over-temperature, reverse polarity, and under-voltage lockout functionality.

Substitute parts are identified when design requirements necessitate alternative packaging formats, extended temperature operating ranges, automotive-grade qualification, or different quiescent current specifications while maintaining core electrical performance parameters.

Parameter Comparison

Engineering Selection Recommendations

TPS79301MDBVREP is designated as the manufacturer-recommended substitute. This part maintains identical electrical specifications to the TPS73001DBVR while offering extended operating temperature range (-55°C to 125°C) and improved quiescent current performance (220 µA versus 250 µA). The primary distinction is packaging format: Tape & Reel (TR) versus Cut Tape (CT) & Digi-Reel®. Selection of this part is appropriate for applications requiring high-volume procurement or extended temperature operation.

TPS73001DBVT is a parametric equivalent offering identical electrical performance and operating temperature range to the TPS73001DBVR. The distinction is limited to packaging format (Tape & Reel versus Cut Tape & Digi-Reel®). This part is suitable for direct substitution when packaging requirements align with Tape & Reel specifications.

TPS79301DBVRG4Q1 and TPS79301DBVRQ1 are parametric equivalents with automotive-grade qualification (AEC-Q100). Both parts feature improved quiescent current (220 µA) and extended PSRR performance (70dB to 43dB across 100Hz to 100kHz). These parts are appropriate for automotive applications or designs requiring AEC-Q100 certification. TPS79301DBVRG4Q1 is available in Cut Tape & Digi-Reel® packaging, while TPS79301DBVRQ1 is also available in Cut Tape & Digi-Reel® packaging.

TPS79301DBVT is a parametric equivalent available in Tape & Reel (TR) packaging. This part offers improved quiescent current (220 µA) and extended PSRR performance compared to the TPS73001DBVR. Selection is appropriate when Tape & Reel packaging is required.

LDK120M-R is designated as a manufacturer-recommended substitute from STMicroelectronics. This part operates within the specified voltage and current parameters but differs in package type (SOT-23-5 versus SOT-23-6), minimum output voltage (0.8V versus 1.22V), and maximum output voltage (5.2V versus 5.5V). Quiescent current is significantly lower (60 µA). This part is suitable for applications where the lower output voltage minimum and reduced quiescent current provide design advantages, provided PCB layout accommodates the SOT-23-5 package footprint.

Frequently Asked Questions (FAQ)

Q: Can TPS79301MDBVREP be used as a direct replacement for TPS73001DBVR?

A: Yes. Both parts maintain identical core electrical specifications: 5.5V maximum input, 1.22V to 5.5V adjustable output range, 200mA output current, and -40°C to 125°C operating temperature. The primary difference is packaging format (Tape & Reel versus Cut Tape & Digi-Reel®). Verify that your procurement and assembly processes accommodate Tape & Reel packaging.

Q: What is the difference between TPS73001DBVT and TPS73001DBVR?

A: These parts are parametrically identical. The distinction is packaging format only: TPS73001DBVT is supplied in Tape & Reel (TR) format, while TPS73001DBVR is supplied in Cut Tape (CT) & Digi-Reel® format. Electrical performance, operating temperature range, and protection features are equivalent.

Q: Are the automotive-qualified parts (TPS79301DBVRG4Q1 and TPS79301DBVRQ1) suitable for non-automotive applications?

A: Yes. Automotive-qualified parts meet or exceed the electrical and reliability specifications of non-automotive equivalents. These parts are appropriate for any application requiring the specified electrical performance and operating temperature range. AEC-Q100 qualification provides additional assurance of manufacturing consistency and reliability.

Q: Can LDK120M-R replace TPS73001DBVR in all applications?

A: LDK120M-R is electrically compatible for applications where the output voltage range (0.8V to 5.2V) and quiescent current (60 µA) specifications are acceptable. The package type differs (SOT-23-5 versus SOT-23-6), requiring PCB layout modification. Verify that your specific output voltage requirements fall within the 0.8V to 5.2V range before selecting this substitute.

Q: What does the quiescent current difference mean for my design?

A: Quiescent current is the supply current drawn by the regulator when no load is connected. TPS73001DBVR draws 250 µA, while TPS79301 variants draw 220 µA, and LDK120M-R draws 60 µA. Lower quiescent current reduces standby power consumption. Selection depends on whether your application prioritizes quiescent current performance or other electrical characteristics.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the compliance status of the TPS73001DBVR.

Q: What is the significance of the extended temperature range (-55°C to 125°C) offered by TPS79301MDBVREP?

A: The extended lower temperature limit (-55°C versus -40°C) allows operation in more extreme cold environments. Applications requiring operation below -40°C should select TPS79301MDBVREP or other parts specifying -55°C minimum operating temperature.
