description/ordering information

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

Zener diodes with a 0.2-Ω 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 (V

) 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.
