Wing Shing WS336Z-5.0 Datasheet
Rev.
Features
• Low temperature coefficient
• Guaranteed temperature stability
•0.6Ω dynamic impedance
• ±1.0% initial tolerance available
• Easily trimmed for minimum temperature drift
Description
The WS336-5.0 integrated Circuits are precision 5.0V
shunt regulators. The monolithic IC voltage references operates 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.
