APPLICATIONS INFORMATION
added as shown in Figure 8 which holds the supply pin of
the LTC1154 high long enough for the overcurrent shutdown
circuitry to respond and fully discharge the gate.
Five volt linear regulators with small output capacitors are
the most diffi cult 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 may

be able to hold the supply pin of the LTC1154 above 3.5V
suffi ciently long that this extra fi ltering is not required.
Because the LTC1154 is micropower in both the standby
and ON state, the voltage drop across the supply fi lter is
less than 2mV, and does not signifi cantly alter the accuracy
of the 100mV drain sense threshold voltage.
