Notes
Deviation of reference input voltage, Vdev, is defined as
the maximum variation of the reference input voltage
over the full temperature range.
The average temperature coefficient of the reference
input voltage, Vref is defined as:
VREF(ppm/°C) = VDEV × 1,000,000
VREF(T1-T2)
The dynamic output impedance, Rz, is defined as:
RZ = ΔVZ
ΔIZ
When the device is programmed with two external
resistors, R1 and R2, (fig 2), the dynamic output
impedance of the overall circuit, R'z, is defined as:
( ) R'Z = RZ 1 + R1
R2
Stability Boundary
The ZTL431 and ZTL432 are stable with a range of
capacitive loads. A zone of instability exists as
demonstrated in the typical characteristic graph on page
4. The graph shows typical conditions. To ensure
reliable stability a capacitor of 4.7nF or greater is
recommended between anode and cathode.
