SEMICONDUCTOR CURRENT REGULATOR AND SWITCH

摘要

A semiconductor current regulating and switching apparatus is described wherein an NMOS enhancement mode power transistor is used in the positive lead to regulate the flow of current from a power source to a load. In order to achieve a low resistance on-state for the NMOS power transistor, the control gate must be biased to a voltage which exceeds the positive voltage of the power source. This bias voltage is generated within the apparatus.
