Description
The
WS336-5.0 integrated Circuits are precision 5.0V
shunt regulators. The monolithic IC voltage references oper-
ates as a low temperature coeffcient 5
.0V zener with 0.6ohm
dynamic impedance. A third terminal on the
WS336-5.0
allow the reference voltage and temperature coefficent to be
trimmed easily.
WS336-5.0 are useful as a precision 5.0V
low voltage reference for digital voltmeters, power supplies
or op amp circuitry. The
5.0V make it convenient to obtain a
stable reference from low voltage supplies. Further, since the
WS336-5.0 operate as shunt regulators, they can be used
as either a positive or negative voltage reference.
