Features
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.
Output voltage range: 1.2 to 37 V
Output current in excess of 500 mA
Line regulation typ. 0.01 %
Load regulation typ. 0.1 %
Thermal overload protection
Short circuit protection
Output transition safe area compensation
Floating operation for high voltage applications
