Operating Ambient Temperature

The ML7900 series are 3-Terminal Negative Voltage Regulators. These negative regulators are intended as complements to

the popular ML7800 series of positive voltage regulations, and they are available in the same voltage options from -5V to -

24V. The ML7900 series employ internal current-limiting. safe-area protection , and thermal shutdown, making them

virtually indestructible.

* Parts of FBE are satisfied with requirements of directive 2002/95/EC on RoHS.
