Fe deo cmisc LM7800 Series 3-Terminal Fixed Voltage Regulators THREE-TERMINAL POSITIVE VOLTAGE REGULATORS ) These voltage regulators are monolithic integrated circuits designed as fixed-voltage regulators for a wide variety of applications including local, on- card regulation. These regulators employ internal current limiting, thermal shutdown, and safe-area FEATURES ) Output Current in Excess of 1.5 Ampere e No External Components Required e Internal Thermal Overload Protection Internal Short-Circuit Current Limiting Output Transistor Safe-Area Compensation e Output Voltage Offered in 2% Tolerance compensation. With adequate heatsinking they can deliver output currents in excess of 1.5 ampere. Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents. PIN ARRANGEMENT to Pin 2.)
