SOT23 MICROPOWER 1.22V VOLTAGE REFERENCE
ZXRE125
SUMMARY
DESCRIPTION
The ZXRE125 is a bandgap circuit designed to achieve a precision micropower
voltage reference of 1.22 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% for precision applications. Excellent
performance is maintained over the 8␮A to 20mA 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 replacement of the ZRA124
and ZRA125 series of voltage references. An E-Line (TO92 style) package is also
available.
