LM336-2 LM336-2.5/B/LM236-2 5/B/LM236-2.5 (KA336-2 KA336-2.5, KA236-2 KA236-2.5) PROGRAMMABLE SHUNT REGULATOR PROGRAMMABLE SHUNT REGULATOR TO-92 The LM336-2 LM336-2.5/B integrated Circuits are precision 2.5V shunt regulators. The monolithic IC voltage references operates as a low temperature coefficient 2.5V zener with 0.2 dynamic impedance. A third terminal on the KA336-2 KA336-2.5/B allow the reference voltage and temperature coefficient to be trimmed easily. LM3362 LM3362.5/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 LM336-2 LM336-2.5/B operate as shunt regulators, they can be used as either a positive or negative voltage reference. 1: Adj. 2: + 3: - FEATURES · Low temperature coefficient · Guaranteed temperature stability 4mV typical · 0.2 dynamic impedance · ±1.0% initial tolerance available. · Easily trimmed for minimum temperature drift ORDERING INFORMATION Device LM336Z-2 LM336Z-2.5 LM336Z-2 LM336Z-2.5B LM236Z-2 LM236Z-2.5 Package TO-92 Operating Temperature 0 ~ +70°C -25 ~ +85°C SCHEMATIC DIAGRAM Rev.
