ZXRE4041 SOT23 MICROPOWER 1.225V VOLTAGE REFERENCE SUMMARY DESCRIPTION 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 30A to 12mA operating current range with a typical temperature coefficient of only 20ppm/C. The device has been designed to be highly tolerant of capacitive loads so maintaining excellent stability. This device offers a SOT23 pin for pin compatible alternative to LM4041 voltage references.
