ABSTRACT:
A voltage regulating circuit for automotive vehicles includes: a supply voltage; a load; and a Positive Temperature Coefficient ("PTC") resistance element connected in series between the supply voltage and the load, for regulating voltage applied from the supply voltage to the load creating by a voltage drop across the PTC element. The PTC element includes a PTC element body substance; electrode plates provided on both side surfaces of the PTC element body substance; connection terminals provided for the respective electrode plates; and a return portion provided for at least one of the electrode plates or the connection terminals, for adjusting resistance of the element.
