TLE7276D Equivalent & Substitute Parts

Part Overview

The TLE7276D is a linear voltage regulator IC manufactured by Infineon Technologies, designed to deliver positive fixed 5V output at 300mA in a TO-252-5 surface mount package. This device is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production support and design continuity. The TLE7276D provides regulated power management with integrated protection features including over-current, over-temperature, and short-circuit protection, suitable for applications requiring stable 5V rails with moderate current demands.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE7276D is determined by strict alignment of electrical and mechanical parameters. The primary criteria for equivalence are:

• Fixed 5V output voltage configuration
• 300mA output current capability
• Maximum input voltage rating of 40V or higher
• Voltage dropout specification of 0.5V or lower at comparable current levels
• Operating temperature range spanning -40°C to 150°C
• TO-252-5 surface mount package compatibility
• Integrated protection against over-current, over-temperature, and short-circuit conditions

The TPS7A6050QKVURQ1 from Texas Instruments meets these substitution criteria while offering active product status and automotive-grade qualification.

Parameter Comparison

Engineering Selection Recommendations

The TPS7A6050QKVURQ1 is a direct functional substitute for the obsolete TLE7276D. Both devices share identical output voltage and current specifications, matching package geometry, and overlapping operating temperature ranges. The TPS7A6050QKVURQ1 maintains active product status with AEC-Q100 automotive qualification and ROHS3 compliance, ensuring long-term availability and supply chain stability. The maximum input voltage of the substitute (40V) remains within acceptable margins for applications designed for the TLE7276D's 42V rating. The additional Under Voltage Lockout (UVLO) protection feature in the substitute provides enhanced system reliability without introducing incompatibility.

Frequently Asked Questions (FAQ)

Q: Can the TPS7A6050QKVURQ1 directly replace the TLE7276D in existing designs?

A: Yes. Both devices deliver 5V at 300mA in TO-252-5 packages with matching operating temperature ranges and dropout specifications. Pin-to-pin compatibility and electrical performance alignment enable direct substitution without circuit modification.

Q: What is the significance of the 2V difference in maximum input voltage (42V vs 40V)?

A: The TPS7A6050QKVURQ1's 40V maximum input rating is sufficient for standard 5V regulator applications. If your design specifically requires operation above 40V input, the TLE7276D's 42V rating may be necessary; however, most industrial and consumer applications operate well within 40V limits.

Q: How does the quiescent current difference (30 µA vs 40 µA) affect system design?

A: The 10 µA difference is negligible in most applications. For battery-powered or ultra-low-power designs where quiescent current is critical, this variance should be evaluated against total system power budget, but it does not prevent substitution in standard applications.

Q: What additional protection does the TPS7A6050QKVURQ1 provide?

A: The substitute includes Under Voltage Lockout (UVLO) protection in addition to the over-current, over-temperature, and short-circuit protection present in the TLE7276D. UVLO prevents regulator operation during low input voltage conditions, enhancing system stability.

Q: Is the TPS7A6050QKVURQ1 suitable for automotive applications?

A: Yes. The TPS7A6050QKVURQ1 carries AEC-Q100 automotive qualification and is graded for automotive use, making it appropriate for automotive and industrial environments requiring enhanced reliability standards.

Q: Are there any compliance or certification differences between the two parts?

A: The TPS7A6050QKVURQ1 is ROHS3 compliant, while the TLE7276D's RoHS status is not specified in the provided data. Both are REACH unaffected and carry EAR99 ECCN classification. For applications with specific compliance requirements, the substitute's documented ROHS3 status provides assurance.
