Vishay Semiconductor  
3-Terminal Fixed Positive Voltage Regulators  
MC78xxCT  
TO-220AB  
Description  
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 shut-  
down, and safe-area compensation. With adequate  
heatsinking the MC78xxCT 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 with currents.  
Standard Application  
Features  
• Output current in excess of 1.0 ampere

0.1µF  
• Internal thermal overload protection  
• Internal short-circuit current limiting  
• Output transistor safe-area compensation  
• Output voltage offered in 2% tolerance  
Notes:  
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.  
Mechanical Data  
Case: TO-220 Package  
xx = these two digits of the part number indicate output voltage.  
Cin is required if regulator is located an appreciable distance from power  
supply filter.  
Case outline is on the back page.  
Co is not needed for stability, however, it does improve transient response.
