TL431ACLPG

参考电压 2.5-36V ADJ 1-100mA

The TL431ACLPG TL431A, B integrated circuits are three−terminal  programmable shunt regulator diodes. These monolithic IC voltage  references operate as a low temperature coefficient zener which is  programmable from Vref to 36 V with two external resistors. These  devices exhibit a wide operating current range of 1.0 mA to 100 mA  with a typical dynamic impedance of 0.22 . 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 2.5 V reference makes it convenient to obtain a  stable reference from 5.0 V logic supplies, and since the TL431ACLPG TL431A, B  operates as a shunt regulator, it can be used as either a positive or  negative voltage reference.
