A circuit includes an OPAMP-less bandgap voltage generating core circuit connected between a regulated voltage and a ground reference to generate an output bandgap voltage. Furthermore, the base substrate is provided on its end portion with a slope crossing a side surface and a rear surface of the base substrate. These compounds can be formulated for oral administration. The aligning member defines a plurality of through holes arranged in parallel in the first direction and extending in a second direction perpendicular to the first direction.
