via monitoring the FB pin.

This pin is pulled low when the voltage is outside the limits, during thermal shutdown and
if either V

CNTL

or V

IN

go below their thresholds.

Enable Pin. Driving this pin low will disable the part. When left floating an internal current
source will pull this pin high and enable it.

Power Input Pin for current supply. Connect a decoupling capacitor (≥10µF) as close as
possible to the pin for noise filtering
