TPS79918DRVT Equivalent & Substitute Parts

Part Overview

The TPS79918DRVT is a linear voltage regulator IC from Texas Instruments designed for positive fixed output applications. It delivers 1.8V at 200mA output current with a maximum dropout voltage of 0.18V at full load. The device integrates protection features including over-current, over-temperature, reverse polarity, and under-voltage lockout (UVLO) protection. It operates across the industrial temperature range of -40°C to 125°C and is housed in a 6-WSON (2x2) surface-mount package. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Identifying equivalent substitute parts is necessary for supply chain continuity, inventory optimization, and design flexibility when the primary part becomes unavailable or when alternative packaging or supplier options are required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS79918DRVT are identified based on strict parametric equivalence across the following critical criteria:

Electrical Parameters (Must Match):

• Output voltage: 1.8V fixed
• Output current capability: 200mA
• Maximum input voltage: 6.5V
• Dropout voltage: 0.18V @ 200mA
• Quiescent current: 60 µA
• PSRR performance: 70dB ~ 38dB (100Hz ~ 100kHz)
• Protection features: Over Current, Over Temperature, Reverse Polarity, UVLO
• Operating temperature range: -40°C to 125°C

Mechanical Parameters (Must Match):

• Package type: 6-WSON (2x2)
• Mounting type: Surface Mount
• Package configuration: 6-WDFN Exposed Pad

Compliance & Status (Must Match):

• Manufacturer: Texas Instruments
• Product status: Active
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

Only parts meeting all these criteria are classified as parametric equivalents. Packaging variants (Cut Tape vs. Digi-Reel) do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The TPS79918DRVR is a direct parametric equivalent to the TPS79918DRVT. Both parts are manufactured by Texas Instruments, maintain active product status, and carry ROHS3 compliance certification. The electrical specifications, thermal operating range, protection feature set, and physical package dimensions are identical. The difference between these part numbers reflects packaging format options (tape reel configuration) rather than functional or performance variation. Selection between TPS79918DRVT and TPS79918DRVR should be based on supply chain availability, inventory management requirements, and procurement preferences for tape reel versus cut tape formats. Both parts are suitable for direct substitution in applications requiring a 1.8V, 200mA linear regulator with the specified protection features and performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can TPS79918DRVR be used as a direct replacement for TPS79918DRVT?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output voltage, current rating, dropout voltage, quiescent current, PSRR, protection features, operating temperature range, and package configuration. The part number suffix reflects packaging format only.

Q: What is the difference between TPS79918DRVT and TPS79918DRVR?

A: The difference is in packaging format. TPS79918DRVT is supplied in Cut Tape (CT) format, while TPS79918DRVR is supplied in Digi-Reel format. Both contain the identical die and deliver the same electrical performance.

Q: Are there any compatibility concerns when substituting between these parts?

A: No compatibility concerns exist. Both parts use the identical 6-WSON (2x2) package with exposed pad, surface-mount configuration, and pinout. PCB layout, solder reflow profiles, and thermal management requirements are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TPS79918DRVT and TPS79918DRVR are ROHS3 compliant, REACH unaffected, carry MSL 1 (unlimited) moisture sensitivity rating, and share identical ECCN and HTSUS classifications.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on supply chain availability, procurement lead times, and inventory management strategy. Both parts are in active production status with equivalent long-term availability.

Q: What is the minimum input voltage requirement for these regulators?

A: The input voltage specification provided indicates a maximum of 6.5V. The minimum input voltage is not specified in the available parameters and must be obtained from the device datasheet.

Q: Can these parts be used in applications requiring extended temperature ranges beyond -40°C to 125°C?

A: No. Both parts are rated for -40°C to 125°C operating temperature. Applications requiring extended temperature ranges require alternative device selection.
