| ZXRE1004 SOT23 MICROPOWER (4A) 1.22V VOLTAGE REFERENCE maintained over the 8A 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 . DESCRIPTION The ZXRE1004 is a 1.22 volt bandgap reference circuit designed for ultra low current operation, typically 4A. 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 FEATURES High performance alternative to REF1004, LT1004 and LM185/385 references 4A typical knee current Small outline SOT23 package SO8 and E-Line alternatives available 20ppm/C typical temperature coefficient Unconditionally stable 0.5%, 1%, 2% and 3% tolerance Contact Zetex marketing for availability of tighter tolerance devices APPLICATIONS Battery powered equipment Precision power supplies Portable instrumentation Portable communications devices Notebook and palmtop computers Data acquisition systems A/D and D/A converters Test equipment VR Gnd SCHEMATIC DIAGRAM APPLICATIONS CIRCUIT Ultra low quiescent reference from a 1.5V battery source.
