Voltage Regulator – Adjustable Output, Positive
1.5 A
LM317, NCV317
The LM317 is an adjustable 3−terminal positive
voltage regulator capable of supplying in excess of 1.5 A over an output
voltage range of 1.2 V to 37 V. This
voltage regulator is exceptionally easy to use and requires only two external resistors to set the output
voltage. Further, it employs internal current limiting, thermal shutdown and safe area compensation, making it essentially blow−out proof.
The LM317 serves a wide variety of applications including local, on card regulation. This device can also be used to make a programmable output regulator, or by connecting a fixed resistor between the adjustment and output, the LM317 can be used as a precision current regulator.
