Key Parameters

Substitute Part Grouping Explanation

The MIC29152WD-TR qualifies as a direct substitute based on the following alignment criteria:

Matching Parameters:

• Identical output current rating: 1.5A
• Identical package type: TO-252-5 (DPAK with 5 leads plus tab)
• Identical voltage dropout specification: 0.6V @ 1.5A
• Identical operating temperature range: -40°C to 125°C
• Identical control features: Enable function
• Identical protection features: Over Current, Over Temperature, Reverse Polarity
• Identical mounting type: Surface Mount
• Identical RoHS and REACH compliance status
• Same manufacturer: Microchip Technology

Key Difference: The MIC29152WD-TR has an expanded input voltage range (26V maximum versus 6V maximum) and adjustable output voltage range (1.25V to 25V versus 1.24V to 5.4V). These expanded specifications make the MIC29152WD-TR suitable for applications requiring the MIC35152WD-TR's performance envelope while offering additional design flexibility for higher voltage applications.
