Note 1: All devices are 100% production tested at T
A
= +25°C and are guaranteed by design for T
A
= T
MIN
to T
MAX
, as specified.
Note 2: This parameter is guaranteed by the “reverse breakdown change with current” test.
Note 3: TC is measured by the “box” method; i.e., (V
MAX
- V
MIN
)/(T
MAX
- T
MIN
).
Note 4: Thermal hysteresis is defined as the change in the +25°C output voltage after cycling the device from T
MIN
to T
MAX
.
