DESCRIPTION

The ZXRE1004 is a 1.22 volt bandgap reference circuit designed for ultra low current operation, typically 4/G02 A. 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 8 /G02 A 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 SO8 and E-Line (TO92 style) equivalents .
