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-
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
Z
) 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.
