100 mA Negative Voltage
Regulators
The MC79L00, A Series negative voltage
regulators are inexpensive, easy–to–use devices suitable for numerous applications requiring up to100 mA. Like the higher powered MC7900 Series negative
regulators, this series features thermal shutdown and current limiting, making them remarkably rugged. In most applications, no external components are required for operation. The MC79L00 devices are useful for on–card regulation or any other application where a regulated negative voltage at a modest www.DataSheet4U.com current level is needed. These
regulators offer substantial advantage over the common resistor/zener diode approach. No External Components Required Internal Short Circuit Current Limiting Internal Thermal Overload Protection Low Cost Complementary Positive
