Substitute Part Grouping Explanation

Substitution of the TPS76518DG4 is determined by strict equivalence across the following critical parameters:

  • Output voltage specification: 1.8V fixed output
  • Output current capability: 150mA minimum
  • Maximum input voltage: 10V
  • Package type: 8-SOIC surface mount
  • Control features: Enable and Power Good functions
  • Protection features: Over Current, Over Temperature, and Reverse Polarity protection
  • Operating temperature range: -40°C to 125°C
  • Regulatory compliance: ROHS3 and REACH status

The TPS76518D qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status and packaging format, with the TPS76518D remaining active in the product portfolio.
