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:

When the device is programmed with two external resistors, R1
and 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.
