3-TERMINAL NEGATIVE VOLTAGE REGULATOR

Micro Electronics 

ML7900

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.
