Low Voltage(1.24V) Adjustable Precision Shunt Regulator
TL432Z/AZ/CZ
The deviation parameters V
REF(DEV)
and I
REF(DEF)
are defined as the differences between the maximum and minimum
values obtained over the recommended temperature range. The average full-range temperature coefficient of the
reference voltage, αV
REF
, is defined as :
Where :
ΔT
A
is the recommended operating free-air temperature range of the device.
αV
REF
can be positive or negative, depending on whether minimum V
REF
or maximum V
REF
, respectively, occurs at the
lower temperature.
Example : Maximum V
REF
=1190 at 30℃, maximum V
REF
=1262 at 0℃, V
REF
=1241 at 25℃, ΔT
A
=125℃
for TL432CZ
Because minimum V
REF
occurs at the lower temperature, the coefficient is positive.
Calculating Dynamic Impedance
The dynamic impedance is defined as :
When the device is operating with two external resistors (see Figure 3), the total dynamic impedance of the circuit
is given by :
