TPS77050DBVR Equivalent & Substitute Parts

Part Overview

The TPS77050DBVR is a linear voltage regulator IC manufactured by Texas Instruments, designed for positive fixed 5V output at 50mA in a SOT-23-5 surface mount package. This device is currently in active production status with 2400 units in stock. The TPS77050DBVR serves applications requiring low-dropout regulation with integrated protection features including over-current, over-temperature, and reverse polarity protection.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or application requirements demand higher output current capacity or improved quiescent current performance while maintaining the same output voltage and package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS77050DBVR are classified based on strict parametric equivalence within the following criteria:

Parametric Equivalent Category: Parts maintaining identical output voltage (5V), input voltage rating (10V max), package type (SOT-23-5), and mounting configuration (surface mount). These parts are direct functional replacements with no circuit redesign required.

Key Substitution Parameters:

• Output Voltage: 5V (fixed)
• Package: SOT-23-5
• Mounting Type: Surface Mount
• Input Voltage Rating: 10V maximum
• Output Configuration: Positive
• Control Features: Enable function present

Manufacturer Recommended Category: Parts exceeding the original specifications in output current capacity while maintaining the same voltage output, package, and mounting type. These parts provide enhanced performance headroom and are suitable for applications where the original 50mA specification may be marginal.

Parameter Comparison

Engineering Selection Recommendations

TPS77050DBVT (Texas Instruments): This part is a parametric equivalent to the TPS77050DBVR with identical electrical specifications. However, the product status is Last Time Buy, indicating limited future availability. Selection of this part should be restricted to applications where existing inventory is available and long-term supply is not a requirement. Both parts maintain ROHS3 compliance and identical operating temperature range (-40°C ~ 125°C).

S-1200B50-M5T1U (ABLIC Inc.): This part provides increased output current capacity (150mA versus 50mA) while maintaining 5V output voltage and SOT-23-5 package compatibility. The quiescent current is significantly reduced (1 µA versus 28 µA), offering improved efficiency in low-power standby conditions. The operating temperature range is limited to -40°C ~ 85°C, which may restrict use in high-temperature applications. ROHS3 compliance is maintained. This part is suitable for applications requiring higher current delivery or extended battery life operation.

S-814A50AMC-BDOT2U (ABLIC Inc.): This part delivers the highest output current capacity (180mA) with the lowest quiescent current (500 nA), providing optimal performance for power-sensitive applications. The operating temperature range is -40°C ~ 85°C. ROHS3 compliance is maintained. The PSRR specification (45dB at 100Hz) is lower than the original part. This part is recommended for applications prioritizing ultra-low standby current consumption and higher current delivery capability.

Frequently Asked Questions (FAQ)

Q: Can TPS77050DBVT be used as a direct replacement for TPS77050DBVR?

A: Yes, TPS77050DBVT is a parametric equivalent with identical electrical specifications and package type. However, verify that inventory availability meets your supply chain requirements, as this part carries Last Time Buy status.

Q: What is the primary difference between the ABLIC substitutes and the original Texas Instruments part?

A: The ABLIC parts (S-1200B50-M5T1U and S-814A50AMC-BDOT2U) offer higher output current capacity (150mA and 180mA respectively) and significantly lower quiescent current. The operating temperature range is reduced to -40°C ~ 85°C. These differences make them suitable for applications requiring higher current delivery or improved efficiency, provided the temperature range is acceptable.

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

A: Yes, all substitute parts use the SOT-23-5 package (SC-74A, SOT-753), ensuring identical PCB footprint and mounting compatibility.

Q: What compliance certifications apply to all listed parts?

A: All parts listed are ROHS3 compliant, REACH unaffected, and carry ECCN classification EAR99. Moisture sensitivity level is 1 (Unlimited) for all parts.

Q: Which substitute part should be selected for applications operating above 85°C?

A: Only the TPS77050DBVR and TPS77050DBVT support the full operating temperature range of -40°C ~ 125°C. The ABLIC substitutes are limited to -40°C ~ 85°C and are not suitable for high-temperature applications.

Q: How do the quiescent current specifications compare across all parts?

A: TPS77050DBVR and TPS77050DBVT both draw 28 µA quiescent current. S-1200B50-M5T1U reduces this to 1 µA, and S-814A50AMC-BDOT2U further reduces it to 500 nA, making the ABLIC parts superior for battery-powered or low-power standby applications.
