description/ordering information
ANODE
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 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.
CATHODE
ADJ
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.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable
ambient temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can impact reliability.
2. The package thermal impedance is calculated in accordance with JESD 51-7.
