ABSTRACT:
A temperature-compensated voltage regulator includes a field effect transistor voltage buffer which receives a high-voltage input and provides a low-voltage output, and a voltage generator having a series connection of a zener diode and at least one p-n junction diode for generating a reference voltage. The voltage generator is coupled between the low-voltage output of the voltage buffer and the input of a current mirror, with the output of the current mirror being coupled to the gate electrode of the field effect transistor in the voltage buffer. Additionally, the output of the current mirror is coupled to the low-voltage output of the voltage buffer by a resistor. The resulting voltage regulator circuit features high performance in a simple, economical configuration.
