ZXRE4041CFTA Diodes Incorporated

A Product Line of Diodes Incorporated ZXRE4041 SOT23 MICROPOWER 1.225V VOLTAGE REFERENCE Description Pin Assignments The ZXRE4041 is a bandgap circuit designed to achieve a precision micropower voltage reference of 1.225 volts. The device is available in the small outline SOT23 surface mount package which is ideal for applications where space saving is important. SOT23 tolerance is available to 0.5% C grade for precision applications. Excellent performance is maintained over the 30 A to 12mA operating current range with a typical temperature coefficient of only 20ppm/C. The device has (Top view) been designed to be highly tolerant of capacitive loads so Pin 1 floating or connected to pin 2 maintaining excellent stability. This device offers a SOT23 pin for pin compatible alternative to LM4041 voltage references.
