Hot-selling and scarce FA431ZCS PROGRAMMABLE PRECISION REFERENCES SOT23 spot stock

Product Descriptions

​

The FA431Z/ZS/ZF integrated circuits are three-terminalprogrammable shunt regulator diodes .

These monolithic IC voltage reference operate as a lowtemperature coefficient zener which is programmable fromV_ref to 40 volts with two external resistors .

These devices exhibit a wide operating current range of 1.0 to 100mAwith a typical dynamic impedance of 0.2Ω .

The characteristics of these references make them excellentreplacements for zener diodes in many applications such as digital voltmeters,power supplies, and op amp circuitry .

The 2.5 volt  reference makes it convenient to obtain a stable  referencefrom 5.0 volt logic supplies, and  since the FA431 Series operates as a shunt regulator, it can be used as either a positive or negative voltage reference .
