Abstract
Abstract An IC built-in connector for power source stabilization including a connector body having a plurality of contacts to be brought into contact with a cable terminal connector, and a wiring board built in the connector body and adapted to have thereon a variable direct voltage converter acting as a power source stabilizing IC. The wiring board has a plurality of output voltage control resistors for the power source stabilizing IC having coefficients of temperature which are generally equal, and the resistors are arranged right under or proximate to a surface of the wiring board where the power source stabilizing IC is mounted, so as to be heated equally thereby, so that a resistance ratio of each IC output voltage control resistor is equally compensated with respect to the temperature of the power source stabilizing IC.
