7812 Voltage Regulator IC

The 7812 IC is a commonly used linear regulator.  Input voltage can range from 12 – 35VDC and it outputs a fixed 12V at over 1A of current and up to 2.2A of surge current. For basic operation, no external components are required. Just hook up the input voltage and ground of the 7812 voltage regulator and you have 5V available on the output.

If you are using it at a fair distance from the supply that is providing the input voltage, then a .33uF or larger input filter capacitor is recommended. The part ideally should be a low ESR part such as a Tantalum or Mylar capacitor, but small electrolytic caps generally work fine.

The LM317 provides a stable, regulated output voltage in the range of 1.2V to 37V and can be adjusted using external resistors. It has a maximum continuous output current of 1.5A, a typical dropout voltage of 1.5V, and operates over a wide range of input voltages (3V to 40V) and temperatures (-40°C to 125°C). The IC features built-in current limiting, thermal shutdown protection, and short-circuit protection.
