TPS7A0512PDBVR Equivalent & Substitute Parts

Part Overview

The TPS7A0512PDBVR is a linear voltage regulator IC manufactured by Texas Instruments, classified as a Power Management (PMIC) component. It delivers a fixed positive output of 1.2V at 200mA with a maximum input voltage of 5.5V and operates across the temperature range of -40°C to 125°C. The device is in Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS7A0512PDBVR are identified based on the following critical parameters that determine functional compatibility:

• Output Voltage (Fixed): Must be 1.2V
• Package Type: Must be SOT-23-5 (SC-74A)
• Output Configuration: Must be Positive
• Output Type: Must be Fixed
• Number of Regulators: Must be 1
• Input Voltage (Max): Must be 5.5V or greater
• Mounting Type: Must be Surface Mount
• RoHS Compliance: Must be ROHS3 Compliant

Two substitute parts meet these criteria: TPS7A0512PDBVT (parametric equivalent from Texas Instruments) and RT9073-12GB (manufacturer-recommended equivalent from Richtek USA Inc.). Both maintain the same output voltage, package configuration, and core electrical specifications required for direct substitution in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

TPS7A0512PDBVT is a parametric equivalent from Texas Instruments with identical electrical specifications to the TPS7A0512PDBVR. Both parts share the same base product number (TPS7A0512), output current rating (200mA), dropout voltage characteristics, and operating temperature range (-40°C to 125°C). This part is suitable for direct substitution with no design modifications required. MSL rating of 1 (Unlimited) provides equivalent moisture handling to the primary part.

RT9073-12GB is a manufacturer-recommended equivalent from Richtek USA Inc. that maintains the same 1.2V output voltage and SOT-23-5 package configuration. This part offers higher output current capability (250mA versus 200mA) and superior PSRR performance (75dB at 1kHz). However, the maximum operating temperature is limited to 85°C (compared to 125°C for the TPS7A0512PDBVR), and the dropout voltage is higher at 1.2V @ 250mA. The RT9073-12GB lacks Under Voltage Lockout (UVLO) protection and has an MSL rating of 3 (168 Hours), requiring more stringent moisture control during handling and storage. Selection of this part is appropriate for applications where the lower maximum operating temperature and higher dropout voltage are acceptable, and where the increased output current capability provides design margin.

Frequently Asked Questions (FAQ)

Q: Can TPS7A0512PDBVT be used as a direct replacement for TPS7A0512PDBVR?

A: Yes. TPS7A0512PDBVT is a parametric equivalent with identical electrical specifications, including output voltage (1.2V), output current (200mA), dropout voltage (0.679V @ 200mA), operating temperature range (-40°C to 125°C), and protection features. No circuit modifications are required.

Q: What are the key differences between TPS7A0512PDBVR and RT9073-12GB?

A: Both parts deliver 1.2V output in SOT-23-5 packages. RT9073-12GB provides higher output current (250mA versus 200mA) and better noise rejection (75dB PSRR versus 40dB). However, RT9073-12GB has a maximum operating temperature of 85°C (versus 125°C), higher dropout voltage (1.2V @ 250mA versus 0.679V @ 200mA), and lacks UVLO protection. MSL rating is 3 (168 Hours) versus 1 (Unlimited).

Q: Is RT9073-12GB suitable for high-temperature applications?

A: No. RT9073-12GB is rated for operation only to 85°C (ambient temperature), whereas TPS7A0512PDBVR operates to 125°C (junction temperature). Applications requiring operation above 85°C must use TPS7A0512PDBVR or TPS7A0512PDBVT.

Q: What is the impact of MSL rating differences?

A: TPS7A0512PDBVR and TPS7A0512PDBVT have MSL 1 (Unlimited moisture sensitivity), allowing indefinite shelf storage without moisture bake-out. RT9073-12GB has MSL 3 (168 Hours), requiring moisture control and potential bake-out procedures before reflow soldering if storage exceeds 168 hours in high-humidity environments.

Q: Can RT9073-12GB be used in applications designed for 200mA output current?

A: Yes. RT9073-12GB is rated for 250mA output current, which exceeds the 200mA requirement. However, verify that the higher dropout voltage (1.2V @ 250mA) and lower maximum operating temperature (85°C) are compatible with your circuit design and thermal environment.

Q: Are all three parts ROHS3 compliant?

A: Yes. TPS7A0512PDBVR, TPS7A0512PDBVT, and RT9073-12GB are all ROHS3 compliant and REACH unaffected.
