摘要
A voltage regulator circuit for a CAN transceiver has a preregulator circuit which reduces an input voltage to a maximum predetermined voltage. The preregulator circuit is built with diffused MOS (DMOS) or drain extended MOS (DEMOS) transistors or laterally diffused MOS (LDMOS) transistors that are usable with the higher input voltages. A main regulator is coupled to the preregulated voltage to generate the output voltage. The main regulator utilizes lower voltage but faster core transistors and is stable without a load capacitance.
