DESCRIPTION/ORDERING INFORMATION
The LM4041 series of shunt voltage references are versatile, easy-to-use references with a vast array of
applications. They require no external resistors or capacitors for operation and are stable with all capacitive
loads. Additionally, the reference offers low dynamic impedance, low noise, and a low temperature coefficient to
ensure a stable output voltage over a wide range of operating currents and temperatures. The LM4041 uses fuse
and Zener-zap reverse breakdown voltage trim during wafer sort to offer four output voltage tolerances, ranging
from 0.1% (max) for the A grade to 1% (max) for the D grade. Thus, a great deal of flexibility is offered to
designers in choosing the best cost-to-performance ratio for their applications. The LM4041 is available in a fixed
(1.225 V nominal) or an adjustable version (which requires an external resistor divider to set the output to a value
between 1.225 V and 10 V).
Packaged in space-saving SC-70 and SOT-23-3 and requiring a minimum current of 45
μ
A (typ), the LM4041
also is ideal for portable applications. The TO-92 package also is available for through-hole packaging needs.
