Description
The KA278R05 is a low-dropout voltage regulator suitable
for various electronic equipments. It provides constant
voltage power source with TO-220 4 lead full mold package.
The dropout voltage of KA278R05 is below 0.5V in full
rated current(2A). This regulator has various functions such
as a peak current protection, a thermal shut down, an
overvoltage protection and an output disable function.
