Voltage regulator for converting supply voltage into suitable voltage for operating respective electronic circuit has switch-on protection circuit with second and third PMOS-FET transistors

摘要

The voltage regulator has an output transistor (MP1) consisting of a first PMOS-FET whose source forms the regulator input and whose drain forms its output, a regulating arrangement (1) whose output feeds the gate of the output transistor tom minimize the deviation between the output voltage and the desired output voltage and a switch-on protection circuit with an arrangement of second (MP2) and third (MP3) PMOS-FET transistors.
