SOT23 MICROPOWER 1.22V VOLTAGE REFERENCE

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

8µA 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.
