PJ7800

PJ7800 Series 3-Terminal Fixed Voltage Positive Regulators T hese voltage regulators are monolithic integrated circuits designed as fixed-voltage regulators for a With adequate heatsinking they can deliver output currents up to 1 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-220 TO-220F wide variety of applications including local, on-card regulation. These regulators employ internal current limiting, thermal shutdown, and safe-area compensation. FEATURES Output Current up to 1 Ampere No External Components Required Internal Thermal Overload Protection Internal Short-Circuit Current Limiting Output Transistor Safe-Area Compensation Output Voltage Offered in 4% Tolerance Pin: 1.Input 2.Ground 3.Output (Heatsink surface connected to Pin 2.) CIRCUIT SCHEMATIC Representative Schematic Diagram Standard Application TYPICAL CONNECTING CIRCUIT A common ground is required between the input and the output voltages. The input voltage must remain typically 2.0V above the output voltage even during the low point on the Input ripple voltage. XX = these two digits of the type number indicate voltage. * = Cin is required if regulator is located an appreciable distance from power supply filter. ** = Co is not needed for stability; however, it does improve transient response. 1-9 2002/01.rev.A PJ7800 Series 3-Terminal Fixed Voltage Positiv...
