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, V
ref
is defined as:
The dynamic output impedance, R
z
, is
defined as:

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:
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 5. The graph
shows typical conditions. To ensure reliable
stability a capacitor of 4.7nF or greater is
recommended between anode and cathode.
