Description

The LM317AT is capable of supplying in excess of 1.5A over 1.2V to 37V output voltage range. It is exceptionally easy to use and require only two external resistors to set the output voltage. the LM317T offers full overload protection available only in IC"s.
Output is short-circuit protected
80 dB ripple rejection
Current limit constant with temperature
Adjustable output down to 1.2V
No capacitors are needed unless the device is situated more than 6 inches from the input filter capacitors in which case an input bypass is needed
