Shunt Regulator

General Description

TO-92

SOT-23

• The LM431 Series ICs are low voltage three-terminal

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

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 V^REF=1.240V: 1.5%, 1.0% and 0.5%.

SOT-89

SOT-23-5

• These ICs are available in 4 packages: TO-92, SOT-23, SOT-23-5 and SOT-89.
