DESCRIPTION

The ZRT040 is a monolithic integrated circuit providing a precise stable reference voltage of 4.01V at 500µA.

The circuit features a knee current of 150µA and operation over a wide range of temperatures and currents.

The ZRT040 is available in a SOT223 package for surface mount applications. This device offers a trim facility whereby the output voltage can be adjusted as shown in Fig.1. This facility is used when compensating for system errors or setting the reference output to a particular value. When the trim facility is not used, the pin should be left open circuit.

FEATURES

• Excellent temperature stability

• Low output noise figure

• Available in three temperature ranges

• 1 and 2 initial voltage tolerance versions available

• No external stabilising capacitor required in most cases

• Low slope resistance

• SOT223 small outline packages
