ZXRE1004
SOT23 MICROPOWER (4µA) 1.22V VOLTAGE REFERENCE
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.
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.
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.
SOT23 tolerance selection is available to 0.5% for
precision applications. Excellent performance is
