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.
- 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.
