The 317 type IC voltage regulators are adjustable 3-terminal positive voltage regulators capable of supplying in excess of 1.5 A over an output voltage range of 1.25 V to 37 V. Unlike other IC regulators designed to provide a fixed output voltage, 317 type IC voltage regulators are widely used adjustable positive voltage regulators available in many different packages intended for surface mounting on circuit boards. They are exceptionally easy to use and require only two external resistors to set the output voltage. For getting a stable output the input voltage must be 2 to 3 volt higher than the output.

The 317 type IC voltage regulators are offered by different manufacturers and can be used in commercial equipment and a variety of other applications including but not limited to those where there is a need for an  adjustable regulated power supply circuitry in a single chip providing 1.2V to 37V DC output voltage with up to 1.5A output current capability and very low external components. Furthermore, they also include many other features like short circuit protection, safe area and over heat protection making them essentially blow-out proof and long term performers.
