ZRT050

DEVICE DESCRIPTION

The ZRT050 is a monolithic integrated circuit

providing a precise stable reference voltage

of 4.9V at 500

µA.

The circuit features a knee current of 150

µA

and ope ra tion over a wide range of

temperatures and currents.

The ZRT050 is available in a 3-pin metal can

package for through hole applications as

well as SOT223 and SO8 packages for

surface mount applications. Each package

option offers a trim facility whereby the

output voltage can be adjusted as shown in

Fig.1 .

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

• Trimmable output

• Excellent temperature stability

• Low output noise figure

• Available in two temperature ranges

• 1 and 2% initial voltage tolerance

versions available

• No external stabilising capacitor

required in most cases

• Low slope resistance

• TO18 package

• SOT223 and SO8 small outline

packages
