  • Fixed/Adjustable 3-terminal Linear voltage regulator
  • Fixed Voltage type:  5V
  • Output current is 800mA
  • In-built Current Limiting and thermal protection.
  • Operating junction temperature is 125°C
  • SOT223 Package

Where to use LM1117 IC?

  • Just like the famous 7805 and LM317, the LM1117 is another Linear Voltage regulator. It is known for its small form factor since it is available as a DCY Package (SMD Component). There are many types of LM1117, the fixed types provide a fixed output voltage of 1.8V, 2.5V, 3.3V or 5V and the variable voltage regulator can have a variable voltage from 1.25V to 13.8V.


Applications:

  • Used for Positive voltage regulations
  • Variable power supply
  • Current limiting circuits
  • Reverse polarity circuits
  • Commonly used in Desktop PC, DVD and other consumer products
  • Used in motor control circuits
  • So if you are looking for SMD component voltage regulator then this IC might be the right choice for you.
