6.2V LOW POWER
PRECISION REFERENCE SOURCE
ISSUE 1 - OCTOBER 1995
ZRT062
DEVICE DESCRIPTION
The ZRT062 is a monolithic integrated circuit
providing a precise stable reference voltage
of 6.17V at 500µA.
The circuit features a knee current of 150µA
and operation over a wide range of
temperatures and currents.
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.
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

NOTES
(a) Output change with temperature (VR)
The absolute maximum difference between
the maximum output voltage and the
minimum output voltage over the specified
temperature range
VR = Vmax - Vmin
(b) Output temperature coefficient (TCVR)
The ratio of the output change with
temperature to the specified temperature
range expressed in ppm/°C
TcVR

VR x 106
VR x T

T= Full temperature range
(c) Operating current (IR)

derated as indicated in maximum ratings.
(d) Slope resistance (RS)
The slope resistance is defined as :
