LM317 Voltage Regulator TO-92
  • LM317 Voltage Regulator TO-92

#177: LM317 Voltage Regulator TO-92


The LM317 (TO-92) is an adjustable 3−terminal voltage regulator
that can supply 100 mA output 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. 
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, 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
