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.
