LM4040
Precision Micropower Shunt Voltage Reference
General Description
Ideal for space critical applications, the LM4040 precision
voltage reference is available in the sub-miniature (3 mm x
1.3 mm) SOT-23 surface-mount package. The LM4040’s ad-
vanced design eliminates the need for an external stabilizing
capacitor while ensuring stability with any capacitive load,
thus making the LM4040 easy to use. Further reducing de-
sign effort is the availability of several fixed reverse break-
down voltages: 2.500V, 4.096V, 5.000V, 8.192V, and
10.000V. The minimum operating current increases from
60 µA for the LM4040-2.5 to 100 µA for the LM4040-10.0. All
versions have a maximum operating current of 15 mA.
The LM4040 utilizes fuse and zener-zap reverse breakdown
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 correction
and low dynamic impedance ensure stable reverse break-
down voltage accuracy over a wide range of operating tem-
peratures and currents.
Also available is the LM4041 with two reverse breakdown
voltage versions: adjustable and 1.2V. Please see the
LM4041 data sheet.
