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.

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.
Features
• Output current in excess of 1.0 ampere
• No external components required
• Internal thermal overload protection
• Internal short-circuit current limiting
• Output transistor safe-area compensation
• Output voltage offered in 2% tolerance
