ZRT062

DEVICE DESCRIPTION

The ZRT062 is a monolithic integrated circuit

providing a precise stable reference voltage

of 6.17V at 500µA.

FEATURES

Trimmable output

•

Excellent temperature stability

Low output noise figure

•

The circuit features a knee current of 150µA

and operation over a wide range of

temperatures and currents.

Available in two temperature ranges

The ZRT062 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. 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.

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

TYPICAL CHARACTERISTICS

NOTES

(a) Output change with temperature (V_R)

Maximum operating current must be

derated as indicated in maximum ratings.

The absolute maximum difference between

the maximum output voltage and the

minimum output voltage over the specified

temperature range

(d) Slope resistance (R_S)

The slope resistance is defined as :

(b) Output temperature coefficient (T_CV_R)

∆I = 5 - 0.5 = 4.5mA (typically)

The ratio of the output change with

temperature to the specified temperature

range expressed in ppm/°C

(e) Line regulation

The ratio of change in output voltage to the

change in input voltage producing it.
