Key Parameters

Substitute Part Grouping Explanation

Substitution for the TPPM0301DRG4 is determined by strict equivalence across the following critical parameters:

• Output Voltage: Fixed 3.3V output
• Output Current: 400mA capacity
• Input Voltage Range: Maximum 5.5V
• Voltage Dropout: 1V @ 400mA
• Package Type: 8-SOIC surface mount
• Protection Features: Over-temperature and reverse polarity protection
• Operating Temperature Range: 0°C ~ 70°C

The TPPM0301DR qualifies as a parametric equivalent based on identical electrical specifications and package configuration. The primary distinction is product status: TPPM0301DRG4 is obsolete while TPPM0301DR is active.
