Description for the LM317L-N

The LM317L-N is an adjustable positive voltage regulator capable of supplying 100 mA overa 1.2-V to 37-V output range. The LM317L-N is easy to use and requires only two external resistorsto set the output voltage. Both line and load regulation are better than standard fixed regulators.The LM317L-N is available packaged in a standard, easy-to-use
TO-92 transistor package.

The LM317L-N offers full overload protection. Included on the chip are current limit,thermal overload protection, and safe area protection. Normally, no capacitors are required unlessthe device is situated more than 6 inches from the input filter capacitors, in which case an inputbypass is required.

The LM317L-N uses floating topology and sees only theinput-to-output differential voltage, therefore supplies of several hundred volts can be regulated,provided the maximum input-to-output differential is not exceeded. The device makes a simpleadjustable switching regulator, a programmable output regulator, or by connecting a fixed resistorbetween the adjustment and output, the LM317L-N can be used as a precision currentregulator.

The LM317L-N is available in a standard 3-pin TO-92 transistor package, the 8-pin SOICpackage, and 6-pin DSBGA package. The LM317L-N is rated for operation over a −40°C to 125°Crange.
