FEATURES  
DESCRIPTION  
Ideal for space critical applications, the LM4041-N  
2
Available in Standard, AEC Q-100 Grade 1  
(Extended Temp. Range) and Grade 3  
(Industrial Temp. Range) Qualified Versions  
(SOT-23 only)  
precision voltage reference is available in the sub-  
miniature SC70 and SOT-23 surface-mount  
packages. The LM4041-N's advanced design  
eliminates the need for an external stabilizing  
capacitor while ensuring stability with any capacitive  
load, thus making the LM4041-N easy to use. Further  
reducing design effort is the availability of a fixed  
(1.225V) and adjustable reverse breakdown voltage.  
The minimum operating current is 60 μA for the  
LM4041-N 1.2 and the LM4041-N ADJ. Both versions  
have a maximum operating current of 12 mA.  
Small Packages: SOT-23, TO-92, and SC70  
No Output Capacitor Required  
Tolerates Capacitive Loads  
Reverse Breakdown Voltage Options of 1.225V  
and Adjustable  
APPLICATIONS  
The LM4041-N utilizes fuse and zener-zap reverse  
breakdown or reference 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  
breakdown voltage accuracy over a wide range of  
operating temperatures and currents.
