SOT23 MICROPOWER 1.22V VOLTAGE REFERENCE

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.
