com PJ7800B Series 3-Terminal Fixed Voltage Positive Regulators 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.
T hese 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 compensation.

) CIRCUIT SCHEMATIC ORDERING INFORMATION Device Operating Temperature 0°C ~ +70°C Package TO-220 TO-220F Representative Schematic Diagram PJ78xxCZ PJ78xxCI Standard Application 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.
