SOT23 MICROPOWER 1.225V VOLTAGE REFERENCE

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

30 A 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.
