Setting Control Temperature
The emitter-base voltage of the control transistor sets the
stabilization temperature for the LTZ1000. With the values
given in the applications, temperature is normally 60°C.
This provides 15°C of margin above a maximum ambient
of 45°C, for example. Production variations in emitter-base
voltage will typically cause about ±10°C variation. Since
the emitter-base voltage changes about 2mV/°C and is
very predictable, other temperatures are easily set.
Becausehighertemperaturesaccelerateaginganddecrease
long-term stability, the lowest temperature consistent with
the operating environment should be used. The LTZ1000A
should be set about 10°C higher than the LTZ1000. This
is because normal operating power dissipation in the
LTZ1000A causes a temperature rise of about 10°C. Of
course both types of devices should be insulated from
ambient. Several minutes of warm-up is usual.
For applications not requiring the extreme precision or
the low noise of the LTZ1000, Linear Technology makes a
broad line of voltage references. Devices like the LT1021
can provide drifts as low as 2ppm/°C and devices such as
the LM399A can provide drifts of 1ppm/°C. Only applica-
tions requiring the very low noise or low drift with time
of the LTZ1000 should use this device. See Application
Notes AN-82 and AN-86 for further information. Consult
the Linear Technology Applications department for ad-
ditional help.
