5.0V LOW POWER

PRECISION REFERENCE SOURCE

ISSUE 1 - OCTOBER 1995

DEVICE DESCRIPTION

The ZRT050 is a monolithic integrated circuit

providing a precise stable reference voltage

of 4.9V at 500 A.

The circuit features a knee current of 150 A

and operation 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

F i g . 1. Thi s f a ci l i t y i s u sed w he n

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.
