The LM236-2.5, LM336-2.5, and LM336B-2.5 integrated circuits are precision 2.5-V shunt regulator diodes. These reference circuits operate as low-temperature-coefficient 2.5-V Zeners diodes with a 0.2- dynamic impedance. A third terminal provided on the circuit allows the reference voltage and temperature coefficient to be trimmed easily.
The series is useful as precision 2.5-V low-voltage references (VZ) for digital voltmeters, power supplies, or operational-amplifier circuitry. The 2.5-V voltage reference makes it convenient to obtain a stable reference from 5-V logic supplies. Devices in this series operate as shunt regulators, and can be used as either positive or negative voltage references.
The LM236-2.5 is characterized for operation from –25°C to 85°C. The LM336-2.5 and LM336B-2.5 are characterized for operation from 0°C to 70°C.
