FEATURES
DESCRIPTION
Ideal for space critical applications, the LM4040-N
2
2.5V/SOT-23 AEC Q-100 Grades 1 and 3
precision voltage reference is available in the sub-
available
miniature SC70 and SOT-23 surface-mount package.
Small Packages: SOT-23, TO-92 and SC70
The LM4040-N's advanced design eliminates the
No Output Capacitor Required
need for an external stabilizing capacitor while
ensuring stability with any capacitive load, thus
Tolerates Capacitive Loads
making the LM4040-N easy to use. Further reducing
Fixed Reverse Breakdown Voltages of 2.048V,
design effort is the availability of several fixed reverse
2.500V,3.000V, 4.096V, 5.000V, 8.192V, and
breakdown voltages: 2.048V, 2.500V, 3.000V,
10.000V
4.096V, 5.000V, 8.192V, and 10.000V. The minimum
operating current increases from 60 μA for the 2.5-V
APPLICATIONS
LM4040-N to 100 μA for the 10.0-V LM4040-N. All
versions have a maximum operating current of

15 mA.
Data Acquisition Systems
The LM4040-N utilizes fuse and zener-zap reverse
