In this paper, we demonstrate a fully integrated linear voltage regulator in silicon carbide NPN bipolar transistor technology, operational from 25 degrees C up to 500 degrees C. For 15-mA load current, this regulator provides a stable output voltage with <2% variation in the temperature range 25 degrees C-500 degrees C. For both line and load regulations, degradation of 50% from 25 degrees C to 300 degrees C and improvement of 50% from 300 degrees C to 500 degrees C are observed. The transient response measurements of the regulator show robust behavior in the temperature range 25 degrees C-500 degrees C.

For 15-mA load current, this regulator provides a stable output voltage with <2% variation in the temperature range 25 degrees C-500 degrees C. For both line and load regulations, degradation of 50% from 25 degrees C to 300 degrees C and improvement of 50% from 300 degrees C to 500 degrees C are observed. The transient response measurements of the regulator show robust behavior in the temperature range 25 degrees C-500 degrees C.File in questo prodotto:
