Abstract
A small-scale semiconductor device having several trimming portions is disclosed. The device includes an auxiliary voltage regulator circuit outputting an output voltage and having a first trimming unit for adjusting the output voltage output from the auxiliary voltage regulator circuit; an auxiliary circuit comparing a first voltage with a second voltage and performing a prescribed operation based on the compared result, where the first voltage is in proportion to the output voltage of the auxiliary voltage regulator circuit and the second voltage is generated by a detecting unit, the auxiliary circuit including a second trimming unit for adjusting the first voltage; and a single test terminal, connected to receive any one of the first voltage and the second voltage, provided as an external terminal of the semiconductor device so as to adjust both the first and the second trimming units.
