Amplifiers

LDO3A1.8VFixed Output

The LM39300R-1.8 is a 3A fixed 1.8V LDO regulator in a TO-263-3 package, suitable for high-current applications requiring low dropout and fast transient response.

Best for

  • PC add-in cards
  • Microprocessor power supplies
  • Battery-powered equipment

Avoid if

  • Applications requiring adjustable output voltage (use LM39302 instead)
  • Applications needing an enable pin or error flag (use LM39301 instead)

Check before use

  • Thermal resistance and heat sinking requirements
  • Output capacitor ESR specifications
