Application Hints
(Continued)
ENABLE
The LP3994 features an active high Enable pin, V
, which
turns the device on when pulled high. When not enabled the
regulator output is off and the device typically consumes
1nA.
If the application does not require the Enable switching
feature, the V
pin should be tied to V
IN
to keep the
regulator output permanently on.
To ensure proper operation, the signal source used to drive
the V
input must be able to swing above and below the
specified turn-on/off voltage thresholds listed in the Electrical
Characteristics section under V
IL
and V
IH
.
