DC Electrical Characteristics

The following limits apply for +3.0 V

DC to +3.6 VDC, unless otherwise noted. Bold face limits apply for TA =TJ over TMIN to

MAX of the operating range; all other limits TA =TJ = 25˚C unless otherwire noted. TA is the ambient temperature of the

LM93; T

J is the junction temperature of the LM93; TD is the junction temperature of the thermal diode.
