DESCRIPTION/ORDERING INFORMATION

The LM4040 series of shunt voltage references are versatile, easy-to-use references that cater to a vast array of

applications. The 2-pin fixed-output device requires no external capacitors for operation and is stable with all

capacitive loads. Additionally, the reference offers low dynamic impedance, low noise, and low temperature

coefficient to ensure a stable output voltage over a wide range of operating currents and temperatures. The

LM4040 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.

Packaged in space-saving SC-70 and SOT-23-3 packages and requiring a minimum current of 45 µA (typ), the

LM4040 also is ideal for portable applications. The LM4040xI is characterized for operation over an ambient

temperature range of –40°C to 85°C. The LM4040xQ is characterized for operation over an ambient temperature

range of –40°C to 125°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.

UNLESS OTHERWISE NOTED this document contains

PRODUCTION DATA information current as of publication date.

Products conform to specifications per the terms of Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
