TL750M05CKTPR Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The TL750M05CKTPR is a linear voltage regulator IC manufactured by Texas Instruments, designed to deliver a fixed positive 5V output at 750mA. This device operates as a single-output positive regulator in a TO-252-3 (DPAK) surface mount package. The part is currently classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TL750M05CKTPR is determined by the following critical parameters:

• Output voltage: 5V fixed
• Output current capability: minimum 750mA
• Package type: TO-252-3 (DPAK)
• Input voltage rating: 26V or higher
• Surface mount mounting type
• Protection features: Over Current, Over Temperature, Over Voltage

Substitute parts must maintain electrical compatibility across these parameters. Parts are grouped into two categories: parametric equivalents from the same manufacturer (Texas Instruments) and manufacturer-recommended alternatives from other suppliers (Rohm Semiconductor).

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TL750M05CKVURG3

The TL750M05CKVURG3 is the direct parametric equivalent from Texas Instruments. It maintains identical electrical specifications including 750mA output current, 0.6V dropout voltage, and 55dB PSRR. The part is in active production status, ensuring long-term availability. Both parts share the same base product number (TL750M05) and package configuration. This is the recommended first choice for direct replacement.

Alternative Substitute: BA05CC0FP-E2

The BA05CC0FP-E2 from Rohm Semiconductor provides higher output current capability (1A versus 750mA) while maintaining the 5V fixed output and TO-252-3 package. This part is suitable for applications where additional current headroom is beneficial. Operating temperature range extends to -40°C, providing wider environmental coverage. Input voltage rating is 25V, which is acceptable for most applications requiring 26V maximum input.

Alternative Substitute: BA78M05FP-E2

The BA78M05FP-E2 from Rohm Semiconductor delivers 500mA output current, which is below the original 750mA specification. This part is suitable only for applications with reduced current requirements. It offers superior PSRR performance (78dB versus 55dB) and extended temperature range to -40°C. The maximum dropout voltage is 2V at 500mA, which is higher than the original specification. Operating temperature maximum is limited to 85°C.

Frequently Asked Questions (FAQ)

Q: Can TL750M05CKVURG3 be used as a direct replacement for TL750M05CKTPR?

A: Yes. The TL750M05CKVURG3 is a parametric equivalent with identical output voltage (5V), output current (750mA), dropout voltage (0.6V @ 750mA), PSRR (55dB), and package type (TO-252-3). Both parts are ROHS3 compliant. The primary difference is product status: the original is obsolete while the substitute is in active production.

Q: What is the key difference between BA05CC0FP-E2 and the original TL750M05CKTPR?

A: The BA05CC0FP-E2 provides higher output current (1A versus 750mA) and extended operating temperature range (-40°C to 125°C versus 0°C to 125°C). Input voltage maximum is 25V instead of 26V. All other critical parameters including 5V output, TO-252-3 package, and ROHS3 compliance remain compatible.

Q: Is BA78M05FP-E2 suitable for applications requiring 750mA output?

A: No. The BA78M05FP-E2 is rated for 500mA maximum output current, which is insufficient for applications requiring 750mA. This part is suitable only for designs with reduced current demands. Additionally, the maximum operating temperature is limited to 85°C.

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

A: Yes. All substitute parts listed use the TO-252-3 (DPAK) package with 2 leads plus tab configuration. Direct PCB layout compatibility is maintained across all alternatives.

Q: What compliance certifications apply to all substitute parts?

A: All parts including the original TL750M05CKTPR and all substitutes are ROHS3 compliant and REACH unaffected. All parts carry EAR99 export classification.
