摘要：
A speed control apparatus for a DC motor operable with a low voltage battery has a reference voltage generating circuit capable of operable with a low voltage such as 1 V and is settable for output voltage and for temperature coefficient independently each other and has a differential amplifier which is operable with a very small input voltage and capable of operable with such a low voltage.
