MC79L18A
Negative Voltage Regulators 100 mA MC79L00A Series The MC79L00A Series negative voltage regulators are inexpensive, easy−to−use devices suitable for numerous applications requiring up to 100 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 MC79L00A devices are useful for on−card regulation or any other application where a regulated negative voltage at a modest current level is needed. These regulators offer substantial advantage over the common resistor/Zener diode approach. Features • No External Components Required • Internal Short Circuit Current Limiting • Internal Thermal Overload Protection • Low Cost • Complementary Positive Regulators Offered (MC78L00 Series) • Pb−Free Packages are Available www.onsemi.com THREE−TERMINAL LOW CURRENT NEGATIVE FIXED VOLTAGE REGULATORS 8 1 SOIC−8 D SUFFIX CASE 751 P.
