Features
• Low temperature coefficient • Guaranteed temperature stability 4mV typical • 0.2Ω dynamic impedance • ±1.0% initial tolerance available • Easily trimmed for minimum temperature drift
Description
The KA336-2.5/B integrated Circuits are precision 2.5V shunt regulators. The monolithic IC voltage references operates as a low temperature coeffcient 2.5V zener with 0.2W dynamic impedance. A third terminal on the KA336-2.5/B allow the reference voltage and temperature coefficent to be trimmed easily. KA336-2.5/B 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 KA336-2.5/B operate as shunt regulators, they can be used as either a positive or negative voltage reference.
