Data Sheet
ENABLE FEATURE
The
pin under normal operating conditions. As shown in Figure 25,
when a rising V
turns on. When a falling V
threshold, VOUT turns off.
As shown in Figure 25, the EN pin has hysteresis built in. This
prevents on/off oscillations that can occur due to noise on the
EN pin as it passes through the threshold points.

The EN pin active/inactive thresholds derive from the V
therefore, these thresholds vary with the changing input voltage.
Figure 26 shows the typical EN active/inactive thresholds when
the input voltage varies from 1.65 V to 6.5 V.
