LM4041
1.225V Precision micropower shunt voltage reference
Description
Ordering information
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 surface mount
packages which is ideal for applications
where space saving is important.
The LM4041 is available to 0.5% C grade for
precision applications. Excellent performance
is maintained over the 60 A 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.
This device offers a pin for pin compatible
alternative to the LM4041 voltage reference.
