ML7900 - FBE*
SERIES
3-TERMINAL NEGATIVE
VOLTAGE REGULATOR
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.
