SOT23 MICROPOWER (4µA) 1.22V VOLTAGE REFERENCE
Description
Pin Assignments
The ZXRE1004 is a 1.22 volt bandgap reference circuit
designed for ultra low current operation, typically 4μA. The
device is available in a SOT23 surface mount package
offering the ultimate in space and power saving. These
features make the ZXRE1004 particularly suitable for
portable and battery powered applications.
SOT23 Package Suffix - F
SOT23 tolerance selection 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.

As well as the SOT23, the ZXRE1004 can offer a pin for pin
compatible alternative to the REF1004, LT1004 and
LM185/385 series of voltage references with an E-Line
(TO92 style) equivalent.
