1. Use purpose

42117/42118 series circuit is a precision voltage stabilized negative power supply especially designed for operations under high temperature and wide temperature environment, this power supply has the characteristics that output doesn’t change as the input voltage, load current and environment temperature, without connection with the external filter capacitance, the output noise is less than 1mV, and can operate reliably for long term period under shell temperature of 200℃. In addition, the voltage regulation factor and load regulation are smaller compared with foreign products of the same model.
