Description

The ZXRE330 is a low knee current 3.3V voltage reference. Offering tight tolerances and sharp knee characteristics – consuming only 1μA when the 3.3V reference voltage can no longer be maintained.
 
Excellent performance is maintained over the 1μA to 5mA operating current range. The device has been designed to be highly tolerant of capacitive loads so maintaining excellent stability. It’s available in small outline SOT23 and TO92 packages This device offers a pin for pin compatible alternative to industry standard shunt voltage reference.
