MC78T00 Series
3.0 A Positive
Voltage Regulators
This family of fixed
voltage regulators are monolithic integrated circuits capable of driving loads in excess of 3.0 A. These three−terminal regulators employ internal current limiting, thermal shutdown, and safe−area compensation. Devices are available with improved specifications, including a 2% output
voltage tolerance, on AC−suffix 5.0 V, 12 V and 15 V device types.
Although designed primarily as a fixed
voltage regulator, these devices can be used with external components to obtain adjustable
voltages and currents. This series of devices can be used with a series−pass transistor to supply up to 15 A at the nominal output
voltage.

Figure 1. Simplified Application
A common ground is required between the input and the output
voltages. The input
voltage must remain typically 2.2 V 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. ** (See Applications Information for details.) *...
