SOT23 MICROPOWER 1.22V VOLTAGE REFERENCE

DESCRIPTION

typical temperature coefficient of only 20ppm/°C. The

device has been designed to be highly tolerant of

capacitive loads so maintaining excellent stability.

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.

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.

SOT23 tolerance is available to 0.5% for precision

applications. Excellent performance is maintained

over the 30µA to 5mA operating current range with a
