A
TYPICAL APPLICATIO S
Five volt linear regulators with small output capacitors
are the most difficult to protect as they can “switch”
from a voltage mode to a current limited mode very
quickly. The large output capacitors on many switching
regulators, on the other hand, may be able to hold the
supply pin of the LTC1153 above 3.5V sufficiently long
that this extra filtering is not required.

**
Because the LTC1153 is micropower in both the standby
and ON state, the voltage drop across the supply filter
is less than 2mV, and does not significantly alter the
accuracy of the 100mV drain sense threshold voltage.
