DC Electrical Characteristics
(Continued)
The following limits apply for +3.0 V
to +3.6 V
DC
, unless otherwise noted.
Bold face limits apply for T
= T
over T
to
T
of the operating range;
all other limits T
= T
J
= 25C unless otherwise noted. T
is the ambient temperature of the
LM94; T
J
is the junction temperature of the LM94; T
D
is the junction temperature of the thermal diode.
