Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLE4276GVATMA1 is determined by strict equivalence across the following critical parameters:

• Output configuration and type (Positive Adjustable)
• Current output rating (400mA)
• Input voltage maximum (40V)
• Output voltage range (2.5V to 20V)
• Voltage dropout specification (0.5V @ 250mA)
• Quiescent current (200 µA)
• PSRR performance (54dB @ 100Hz)
• Protection feature set (Over Current, Over Temperature, Reverse Polarity, Short Circuit)
• Operating temperature range (-40°C to 150°C)
• Automotive grade and AEC-Q100 qualification
• RoHS3 compliance and MSL rating

The TLE4276GVATMA3 meets all these criteria and qualifies as a direct substitute. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The TLE4276GVATMA3 is the qualified substitute for the discontinued TLE4276GVATMA1. Both parts share identical electrical specifications, protection features, and automotive-grade certifications (AEC-Q100). The substitution is electrically and functionally transparent.

The key distinction is product status and packaging availability. The TLE4276GVATMA1 is discontinued, while the TLE4276GVATMA3 maintains active production status with current inventory availability. The TLE4276GVATMA3 is supplied in Tape & Reel (TR) format, which is standard for high-volume manufacturing and automated assembly processes.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), ensuring compatibility with modern manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can TLE4276GVATMA3 directly replace TLE4276GVATMA1 in existing designs?

A: Yes. The TLE4276GVATMA3 is electrically and functionally identical to the TLE4276GVATMA1 across all specified parameters. No circuit modifications are required. Both parts are housed in the same TO-263-6 (D2PAK) package with identical pinout and electrical characteristics.

Q: What is the difference between these two part numbers?

A: The primary difference is product status and packaging format. The TLE4276GVATMA1 is discontinued, while the TLE4276GVATMA3 is in active production.
