Three-Terminal Positive

Voltage Regulators

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 they can deliver output currents in excess of 1.0 A. Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents.

•Output Current in Excess of 1.0 A

•No External Components Required

•Internal Thermal Overload Protection

•Internal Short Circuit Current Limiting

•Output Transistor Safe±Area Compensation

•Output Voltage Offered in 2% and 4% Tolerance

•Available in Surface Mount D2PAK and Standard 3±Lead Transistor Packages

•Previous Commercial Temperature Range has been Extended to a Junction Temperature Range of ±40°C to +125°C

STANDARD APPLICATION

Input	MC78XX	Output
Cin*		CO**
0.33 μF

A common ground is required between the input and the output voltages. The input voltage must remain typically 2.0 V above the output voltage even during the low point on the input ripple voltage.

XX, These two digits of the type number indicate nominal 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. Values of less than 0.1 μF could cause instability.
