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 shutdown, 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. Output

transistor safe-area compensation Output voltage offered in 2% tolerance
Cin 0.33µF
Co 0.1µF
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. 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. Co is not needed for stability, however, it does improve transient response.
