LM78__AD

1A Standard Positive
Voltage Regulator
LM78xxA
1A Standard Positive Voltage Regulator
General Description
• The LM78xxA series is three terminal standard positive voltage regulator designed for
a wide range of applications that required supply current up to 1A.
TO-220
• The LM78xxA series is available in 7 fixed output voltage:5V,6V,8V,9V,12V,15V and 18V.
• The LM78xxA series provides internal current limiting, thermal shutdown protection and
Safe-area operation compensation which make them virtually immune from output load,
and the output current could up to 1A if adequate heat sinking provide
TO-220F
• The LM78xxA is available in TO-220,TO-220F and DPAK (TO-252) packages.

Note1: Absolute maximum ratings indicate limits beyond which damage to the device may occur.
Recommend operating ratings indicate conditions for which the device is functional, but do not guarantee
specific specification limits. For guarantee specification and test conditions, see the Electrical Characteristics,
the guarantee specification apply only for the test conditions listed. Some performance characteristics may
degrade when the device is not operated under the listed test conditions.
