Precision Micropower Shunt Voltage
Reference
General Description
Ideal for space critical applications, the LM4040 and
LM4041 precision voltage references are available in the
subminiature (3mm × 1.3mm) SOT-23 surface-mount
package.
The LM4040 is available in fixed reverse breakdown
voltages of 2.500V, 4.096V, and 5.000V. The LM4041 is
available with a fixed 1.225V or an adjustable reverse
breakdown voltage.
The minimum operating current ranges from 60μA for the
LM4041-1.2 to 74μA for the LM4040-5.0. LM4040 versions
have a maximum operating current of 15mA. LM4041
versions have a maximum operating current of 12mA.
The LM4040 and LM4041 have bandgap reference
temperature drift curvature correction and low dynamic
impedance, ensuring stable reverse breakdown voltage
accuracy over a wide range of operating temperatures and
currents.
Datasheets and support documentation are available on
Micrel’s web site at: www.micrel.com.
