SOT23 MICROPOWER (4A) 1.22V VOLTAGE REFERENCE
ZXRE1004
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
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 .
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
