The ability to maintain shutoff is shown on the curve
Shutdown Supply Current vs Temperature in the Typical
Performance Characteristics section. At very high
elevated temperatures it is important to hold the shut-
down pin close to the negative supply to keep the supply
current from increasing.

There are several precautions the user should take when
using the LT1190 in order to realize its full capability.
Although the LT1190 can drive a 50pF load, isolating the
capacitance with 10 can be helpful. Precautions prima-
rily have to do with driving large capacitive loads.
