Note 1: A 0.2 µF capacitor in series with a 1

Ω 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 150˚C maximum junction temperature and a thermal resistance of 4˚C/W

junction to case.
