3-Terminal 1A Positive Voltage Regulator
General Description
The LM78XX series of three terminal positive regulators are
available in the TO-220 package and with several fixed output
voltages, making them useful in a wide range of applications.
Each type employs internal current limiting, thermal shut down
and safe operating area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver
over 1A output current. Although designed primarily as fixed
voltage regulators, these devices can be used with external
components to obtain adjustable voltages and currents.
Features
O Output Current up to 1A
O Output Voltages of 5, 6, 8, 9, 12, 15, 18, 24
O Thermal Overload Protection
O Short Circuit Protection
O Output Transistor Safe Operating Area Protection

Note 1: Absolute maximum ratings are those values beyond which damage to the device may occur. The datasheet specifications should be met, without exception, to ensure
that the system design is reliable over its power supply, temperature, and output/input loading variables. Fairchild does not recommend operation outside datasheet specifications.

Note: To specify an output voltage, substitute voltage value for “XX”. A common ground is required between the Input and the Output voltage. The input voltage must remain typically 2.0V above the output voltage even during the low point on the input ripple voltage.
Note: CI is required if regulator is located an appreciable distance from the power supply filter.
Note: CO improves stability and transient response.
