Applications Information (Continued)

the LM 2926/7 may fail to bring the processor under control.

The LM2926/7 reset output may be more efficiently em-

ployed in certain applications as a means of defeating

memory WRITE lines, clocks, or external loads, rather than

depending on unspecified microprocessor operating condi-

tions.

In critical applications the microprocessor reset input should

be fully characterized and guaranteed to operate until the

clock ceases oscillating.

INPUT TRANSIENTS

The LM2926/7 are guaranteed to withstand positive input

transients to 80V followed by an exponential decay of

τ = 20 ms (t

f = 100 ms, or 5 time constants) while maintain-

ing an output of less than 7V. The regulator remains opera-

tional to 26 V

DC, and shuts down if this value is exceeded.
