PRECISION MICROPOWER SHUNT VOLTAGE REFERENCES

Description

Pin Assignments

LM4041_F (SOT23)

The LM4041 is a bandgap circuit designed to achieve a

precision micro-power voltage reference of 1.225 V. The

device is available in the small outline SOT23 and SC70-5

surface mount packages which are ideal for applications

where space saving is important.

ANODE

Pin 3 must left floating or connected to pin 2.

Both packages are available to 0.5% C grade and 1%

D grade for precision applications. Excellent performance is

maintained over the 60µA to 12mA operating current range

with a typical temperature coefficient of only 20ppm/°C. The

device has been designed to be highly tolerant of capacitive

loads so maintaining excellent stability.
