3 Description

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 maintain 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% (maximum) for the A grade to 1% (maximum) 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 45μA

(typical), 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.
