1A Standard Positive
Voltage Regulator
LM7847 ~ LM7824
1A Standard Positive Voltage Regulator
General Description
• The LM78xx 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 LM78xx series is available in 10 fixed output voltage:4.7V,5V,6V,7V,8V,9V,10V,
12V,15V,18V and 24V.
• The LM78xx 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 LM78xx is available in TO-220,TO-220F,DPAK (TO-252) ,D2PAK(TO-263)packages.
.
Features
