REF50Z/REF50D

5V MICROPOWER PRECISION REFERENCE

JUNE 1993

The REF50Z and REF50D are integrated circuits using

the bandgap principle to provide a precise stable reference

voltage of 5V. There are two package options available:

REF50Z in a plastic 3-pin TO-92 and REF50D in a miniature

surface mount package (MP8).

These references feature a recommended operating cur-

rent of 60

µA to 5mA which make them ideal for all low power

and battery applications.
