SOT23 MICROPOWER 1.225V VOLTAGE REFERENCE
Description
Pin Assignments
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.
