The LM317 (TO-92) is an adjustable 3−terminal voltage regulatorthat can supply 100 mA output over an output voltage range of1.2 V to 37 V. This voltage regulator is exceptionally easy to use andrequires only two external resistors to set the output voltage. The LM317 is a robost regulator with internal current control, thermal blow-out protection and perfect for precision control of the current in a circuit.
The LM317 serves a wide variety of applications including local, oncard regulation. This device can also be used to make a programmableoutput regulator, or by connecting a fixed resistor between theadjustment and output, the LM317 can be used as a precision currentregulator.
