AMS1117-3.3RG

PMIC - Voltage Regulators - Linear

LDO3.3VVoltage RegulatorSOT-223

The AMS1117-3.3RG is a reliable 800mA fixed 3.3V LDO regulator in a SOT-223 package, suitable for general-purpose power management.

Best for

  • 3.3V logic power rails
  • Consumer electronics
  • General purpose voltage regulation

Avoid if

  • High input-to-output voltage differential (leads to high power dissipation)
  • Applications requiring ultra-low quiescent current

Check before use

  • Thermal dissipation requirements
  • Output capacitor ESR requirements
