Low Power-Loss Voltage Regulators

PQ05RF2/PQ05RF21/PQ05RF2V Series

s Outline Dimensions (PQ05RF2A/PQ05RF2B Series)

Note) The value of absolute maximum ratings and electrical characteristics is same as ones of PQ05RF2/21series.

s Precautions for Use

(1) Minute adjustment of output voltage (PQ05RF2V series)

If the external resistor is attached to the terminals ™, £ and ¢, minute adjustment of output voltage is possible.

(Refer to the example of basic circuit (PQ05RF2V series) and Fig.5 to 8.)
