LM78XX
3-Terminal
Positive voltage Regulators
DESCRIPTION
These voltage regulators are designed as fixed-voltage regulators for a wide variety
of applications including local, on-card regulation. Although designed primarily as a
fixed voltage regulator, these devices can be used with external components to
obtain adjustable voltages and currents.
FEATURES
Output current in excess of 1.5A
No external components required
Output Voltages (5V, 6V, 8V, 9V, 10V, 12V, 15V, 18V)
Internal Thermal shutdown and SOA protection
Output voltage offered in 4% Tolerance
Pb-Free Packages are available
High ESD Level (HBM>8000V, MM>800V)
TYPICAL APPLICATION
The input voltage must remain typically
2.0V above the output voltage even during
the low point on the ripple voltage.
* CI is required if regulator is located
an appreciable Distance from power filter.
* CO improves transient response.
Values of 0.1 µF could cause instability.

Stresses exceeding Maximum ratings may damage the device. Maximum ratings are stress ratings.
Functional operation above the recommended operating conditions is not implied.
Extended exposure to stresses the above the recommended operating conditions may affect
device reliability.
PD(max) = (TJ(max)–TA) ÷ θJA. Exceeding the maximum allowable power dissipation will result in
excessive die temperature, and the regulator will go into thermal shutdown.
