LM431L LM431LA LM431LB
Shunt Regulator
General Description
• The LM431 Series ICs are low voltage three-terminal
TO-92
programmable shunt regulators with guaranteed thermal
stability over a full operation range. These monolithic ICs
voltage reference operate as a low temperature coefficient
Zener which is programmable from Vref to 18V with two external
resistors. These devices exhibit a wide operating current range
of 80µA to 50/100mA with a typical dynamic impedance of 0.05 to
SOT-23-5
0.22Ω. The characteristics of these references make them excellent
replacements for Zener diodes in many applications such as
digital voltmeters, power supplies and op amp circuitry
• The LM431L precision reference is offered in three voltage
tolerance for VREF=1.240V: 1.5%, 1.0% and 0.5%.
• These ICs are available in 4 packages: TO-92, SOT-23, SOT-23-5 and SOT-89.
