SC1004(A)
Precision Shunt
Voltage Reference
POWER MANAGEMENT
Revision 2, May 2003
The SC1004(A) is a two terminal precision voltage
reference with thermal stability guaranteed over
temperature. The SC1004(A) has a typical dynamic
output impedance of 0.2
. Active output circuitry
provides a very sharp turn on characteristic - the
minimum operating current is 20A, with a maximum of
20mA.
The SC1004(A) is ideally suited for very low power
circuitry such as temperature sensors and portable
meters. It is available with an initial tolerance of 0.8%
(0.32% for SC1004A), and with a voltage option of
1.235V and is offered in a small SO-8 package.
Trimmed bandgap design (0.8% for SC1004,
0.32% for SC1004A version)
Wide operating current range: 20A to 20mA
Low dynamic impedance (0.2
)
Fully stable with all combinations of operating
current/bypass cap. (down to no bypass cap.)
