SOT23 MICROPOWER 1.225V VOLTAGE REFERENCE
SUMMARY
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/°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.
