SOT23 MICROPOWER (4µA) 1.22V VOLTAGE REFERENCE
Description
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 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.
