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
