Description  
ꢀeatures  
The SC4040 is a two terminal precision voltage  
reference with thermal stability guaranteed over  
temperature. The SC4040 has a typical dynamic output  
impedance of 0.25Ω. Active output circuitry provides a  
very sharp turn on characteristic - the minimum  
operating current is 80µA, with a maximum of 20mA.  
u Trimmed bandgap design (0.1%)  
u Wide operating current range 80µA to 20mA  
u Low dynamic impedance (0.25Ω)  
u Industrial temperature range  
u Available in SOT-23-3, TO-92 and SO-8 packages  
Applications  
Available with five voltage tolerances (0.1%, 0.2%, 0.5%,  
1.0% and 2.0%) and three package outlines (SOT-23-3,  
SO-8 and TO-92), this part allows the designer the  
opportunity to select the optimum combination of cost  
and performance for their application.
