LM78XX/LM78XXA
3-Terminal 1A Positive Voltage Regulator
Features
General Description
■ Output Current up to 1A
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 pro-
tection, 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 com-
ponents to obtain adjustable voltages and currents.
■ Output Voltages of 5, 6, 8, 9, 10, 12, 15, 18, 24
■ Thermal Overload Protection
■ Short Circuit Protection
■ Output Transistor Safe Operating Area Protection

Absolute Maximum Ratings
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.

Notes:
1. 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.
2. C is required if regulator is located an appreciable distance from power supply filter.

3. C improves stability and transient response.
