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 30µA to 5mA 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. SO8 and E-Line (TO92 style) packages can also be made available.
