TPS793285DBVT Equivalent & Substitute Parts

Part Overview

The TPS793285DBVT is a linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) component. It delivers a fixed positive output of 2.85V at 200mA in a SOT-23-5 surface mount package. The device is currently marked as Obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. This regulator includes integrated protection features for over-current, over-temperature, reverse polarity, and under-voltage lockout conditions.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TPS793285DBVT is determined by the following critical parameters:

Primary Substitution Criteria:

• Fixed output voltage of 2.85V
• SOT-23-5 package compatibility
• Surface mount mounting type
• Output current capability (minimum 200mA for direct replacement)
• Input voltage rating (5.5V or higher)
• Dropout voltage performance
• Protection features (over-current, over-temperature, under-voltage lockout)

Substitution Categories:

1. Direct Parametric Equivalent – Identical electrical specifications and packaging
2. Manufacturer Recommended Upgrade – Enhanced performance with higher current capability or improved specifications
3. Functional Equivalent – Same output voltage and package with acceptable parameter variations

Parts are grouped based on whether they meet the full electrical and mechanical requirements of the original device or offer improved performance characteristics while maintaining compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): TPS793285DBVR is the parametric equivalent with identical electrical characteristics and SOT-23-5 packaging. This part is in Last Time Buy status, providing a transition path from the Obsolete TPS793285DBVT.

For Active Production (Recommended Upgrade): TPS7A20285PDBVR from Texas Instruments is the manufacturer-recommended substitute. It offers improved performance with 300mA output current capability (versus 200mA), significantly lower quiescent current (15 µA versus 220 µA), and better dropout voltage (0.145V @ 300mA). The part is Active status and ROHS3 compliant, ensuring long-term availability.

For Alternative Manufacturers: RT9193-2HGB from Richtek provides 300mA output current in SOT-23-5 packaging with Active product status. MIC5255 and MIC5265 series from Microchip Technology offer 150mA output current with ROHS3 compliance and Active status, suitable for applications where current requirements are lower than the original 200mA specification.

Compliance Considerations: All recommended substitutes maintain ROHS3 compliance and EAR99 export classification. Moisture sensitivity levels are consistent across alternatives (MSL 1 or MSL 3), with no impact on handling or storage requirements for standard applications.

Frequently Asked Questions (FAQ)

Q: Can TPS7A20285PDBVR directly replace TPS793285DBVT in all applications? A: Yes, for applications requiring 200mA or less. TPS7A20285PDBVR provides higher current capability (300mA), lower quiescent current, and improved dropout voltage performance. The fixed output voltage (2.85V), SOT-23-5 package, and protection features are compatible. Verify that the higher maximum input voltage (6V versus 5.5V) and lower operating temperature maximum (125°C versus 150°C) are acceptable for your design.

Q: What is the difference between SOT-23-5 and TSOT-23-5 packages? A: TSOT-23-5 is a thin variant of SOT-23-5 with reduced height. Both are mechanically and electrically compatible for PCB assembly. Verify your PCB layout and component height constraints before selecting between standard SOT-23-5 and TSOT-23-5 variants.

Q: Why do some substitutes have lower output current (150mA) than the original (200mA)? A: MIC5255 and MIC5265 series are rated for 150mA maximum output current. These parts are suitable only for applications drawing 150mA or less. For applications requiring the full 200mA specification, use TPS7A20285PDBVR or RT9193-2HGB.

Q: Is the TPS793285DBVR still available for new designs? A: TPS793285DBVR is in Last Time Buy status, indicating limited availability. For new designs, use TPS7A20285PDBVR (Active status) to ensure long-term supply continuity.

Q: What are the key differences in quiescent current between alternatives? A: TPS7A20285PDBVR has the lowest quiescent current at 15 µA, beneficial for battery-powered applications. MIC5265-2.85YD5-TR offers 2 µA quiescent current for ultra-low-power designs. The original TPS793285DBVT and most alternatives operate at 130–220 µA quiescent current, which is acceptable for standard applications.

Q: Are all substitutes ROHS3 compliant? A: Yes, all recommended substitutes are ROHS3 compliant. TPS7A20285PDBVR shows "Not applicable" for RoHS status but meets equivalent environmental standards. Verify specific compliance documentation with your supplier if required for your application.
