LM4040/4041
Precision Micropower Shunt Voltage Reference
General Description
Ideal for space critical applications, the LM4040 and LM4041
precision voltage references are available in the subminia-
ture (3mm
×
1.3mm) SOT-23 surface-mount package.
The LM4040 is the 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 break-
down voltage.
The LM4040 and LM4041’s advanced design eliminates the
need for an external stabilizing capacitor while ensuring
stability with any capacitive load, making them easy to use.
The minimum operating current ranges from 60
μ
A for the
LM4041-1.2 to 74
μ
A 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 utilizes zener-zap reverse break-
down voltage trim during wafer sort to ensure that the prime
parts have an accuracy of better than
±
0.1% (A grade) at
25
°
C. Bandgap reference temperature drift curvature correc-
tion and low dynamic impedance ensure stable reverse
breakdown voltage accuracy over a wide range of operating
temperatures and currents.
Features
Small SOT-23 package
