ZXRE4041
SOT23 MICROPOWER 1.225V VOLTAGE REFERENCE
DESCRIPTION
The ZXRE4041 is a bandgap circuit designed to
achieve a precision micropower voltage reference of
1.225 volts. The device is available in the small outline
SOT23 surface mount package which is ideal for
applications where space saving is important.
SOT23 tolerance is available to 0.5% C grade for
precision applications. Excellent performance is
maintained over the 30 A to 12mA operating current

range with a typical temperature coefficient of only
20ppm/擄C. The device has been designed to be highly
tolerant of capacitive loads so maintaining excellent
stability.
This device offers a SOT23 pin for pin compatible
alternative to LM4041 voltage references. SO8 and
E-Line (TO92 style) packages can also be made
available.
