Description
THE GM78R05A is a low - dropout voltage regulator,
suitable for various electronic equipments. It provides
constant voltage power source with TO-220 4 leads full
mold package. Dropout voltage of GM78R05A is below
0.5V in full rated current (1A). This regulator has various
function such as peak current protection, thermal shut
down, overvoltage protection and output disable func-
tion.
