SOT23 MICROPOWER (4

DESCRIPTION

The ZXRE1004 is a 1.22 volt bandgap reference circuit

designed for ultra low current operation, typically 4

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
