ZXLT1004
SOT23 MICROPOWER (4µA) 1.22V VOLTAGE REFERENCE
DESCRIPTION
m aintained over the 8µA 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 m aintaining excellent
stability.
The ZXLT1004 is a 1.22 volt bandgap reference circuit
designed for ultra low current operation, typically 4µA.
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 ZXLT1004 particularly
suitable for portable and battery powered applications.
As well as the SOT23, the ZXLT1004 can offer a pin for
pin com patible alternative to the REF1004, LT1004 and
LM185/385 series of voltage references with E-Line
(TO92 style) equivalent.
SOT23 tolerance selection is available to 0.5% for
pre cis io n a p p lica tio n s . Exce lle n t pe rfo rm a nce is
