■ Outline Dimensions (PQ05RF2A/PQ05RF2B Series)
Note) The value of absolute maximum ratings and electrical characteristics is same as ones of PQ05RF2/21series.
■ Precautions for Use
(1) Minute adjustment of output voltage (PQ05RF2V series)
If the external resistor is attached to the terminals ➁, ➂ and ➃, minute adjustment of output voltage is possible.
(Refer to the example of basic circuit (PQ05RF2V series) and Fig.5 to 8.)
