GND This is Power Supply return for VDD Input
DUT drives VOUT to the level representative of
the ambient temperature (DEFAULT)
DUT drives VOUT to the pre-programmed level
representative of trip temperature
Jumper is installed (DEFAULT)
Measure IDD
Jumper is installed across pins 1 and 2 by default.
Otherwise resistor R3 is in series with the DUT
output.
VTEMP drives VOUT through R3, improves
stability when VOUT has heavy capacitive load
