Note 1:
A 0.2 μF capacitor in series with a 1
resistor should be placed as close as possible to pins 3 and 4 for stability.
Note 2:
The LM383 shuts down above 25V.
Note 3:
For operating at elevated temperatures, the device must be derated based on a 150C maximum junction temperature and a thermal resistance of 4C/W
junction to case.
