Description
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.
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.
This device offers a pin for pin compatible alternative to the
LM4041 voltage reference in both adjustable and 1.225V
output variants.
Features

These are stress ratings only. Operation outside the absolute maximum ratings may cause device failure. Operation at the absolute
maximum rating, for extended periods may reduce device reliability.
Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken
when handling and transporting these devices.
