WS336-2.5
Features
• Low temperature coefficient
• Guaranteed temperature stability 4mV typical
• 0.2dynamic impedance
• ±1.0% initial tolerance available
• Easily trimmed for minimum temperature drift
Description
The WS336-2.5 integrated Circuits are precision 2.5V
shunt regulators. The monolithic IC voltage references oper-
ates as a low temperature coeffcient 2.5V zener with 0.2ohm
dynamic impedance. A third terminal on the WS336-2.5
allow the reference voltage and temperature coefficent to be
trimmed easily. WS336-2.5 are useful as a precision 2.5V
low voltage reference for digital voltmeters, power supplies
or op amp circuitry. The 2.5V make it convenient to obtain a
stable reference from low voltage supplies. Further, since the
WS336-2.5 operate as shunt regulators, they can be used
as either a positive or negative voltage reference.
