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
碌A
(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 鈥?0掳C to 85掳C. The
LM4041xQ is characterized for operation over an ambient temperature range of 鈥?0掳C to 125掳C.
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.
