DESCRIPTION/ORDERING INFORMATION
The LM4041 series of shunt voltage references are versatile, easy-to-use references suitable for a wide array of
applications. They require no external 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).
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas
Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of the Texas
Instruments standard warranty. Production processing does not
necessarily include testing of all parameters.

Packaged in space-saving SC-70 and SOT-23-3 and requiring a minimum current of 45 µA (typ), the LM4041
also is ideal for portable applications. The TO-92 package also is available for through-hole packaging needs.
The LM4041xI is characterized for operation over an ambient temperature range of –40°C to 85°C. The
LM4041xQ is characterized for operation over an ambient temperature range of –40°C to 125°C.
