DESCRIPTION
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 60µA, with a maximum of 20mA.
Available with five voltage tolerances (0.1%, 0.2%, 0.5%, 1.0% and 2.0%) and three package outlines (SOT-23, SO-8 and TO-92), this part allows the designer the opportunity to select the optimum combination of cost and performance for their application.
FEATURES
•Trimmed bandgap design (0.2%)
•Wide operating current range 60µA to 20mA
•Low dynamic impedance (0.25Ω )
•Available in SOT-23, TO-92 and SO-8
APPLICATIONS
•Cellular telephones
•Portable computers
•Instrumentation
•Automotive
