Description
The LM217M/LM317M are monolithic integrated
circuits in TO-220 and DPAK packages intended
for use as positive adjustable voltage regulators.
They are designed to supply until 500 mA of load
current with an output voltage adjustable over a
1.2 to 37 V range.
The nominal output voltage is selected by means
of only a resistive divider, making the device
Table 1.
