description
The LM236-2.5 and LM336-2.5 integrated
circuits are precision 2.5-V shunt regulator
diodes. These monolithic references 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 easily
trimmed.

The series is useful as precision 2.5-V low-voltage
references (V
) for digital voltmeters, power
Z
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 is 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),
ambient temperature is PD = (TJ(max) – TA)/
2. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace
length of zero.
