Key Parameters

Substitute Part Grouping Explanation

Substitution for the TLE4253GSXUMA3 is determined by strict equivalence across the following critical parameters:

• Output current capability: 250mA
• Maximum input voltage: 40V
• Dropout voltage: 0.6V @ 200mA
• Output configuration: Positive adjustable
• Package type: 8-SOIC (PG-DSO-8)
• Automotive qualification: AEC-Q100
• Operating temperature range: -40°C ~ 150°C
• Protection features: Over-temperature, reverse polarity, short circuit

The TLE4253GSXUMA4 meets all these criteria and is therefore a direct functional equivalent. The primary distinction is product status: TLE4253GSXUMA4 is active in production, whereas TLE4253GSXUMA3 is discontinued.
