ZXRE1004
SOT23 MICROPOWER (4 A) 1.22V VOLTAGE REFERENCE
m aintained over the 8 A to 20m A operating current
range with a typical tem perature 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 4 A.
The device is available in a SOT23 surface m ount
package offering the ultim ate in space and power
saving. These features m ake the ZXRE1004 particularly
suitable for portable and battery powered applications.
As well as the SOT23, the ZXRE1004 can offer a pin for
pin com patible alternative to the REF1004, LT1004 and
LM185/385 series of voltage references with SO8 and
E-Line (TO92 style) equivalents .
SOT23 tolerance selection is available to 0.5% for
pre cision applications. Excellent perform ance is
