Pin function
Output current detection pin.
To detect output current as a voltage,
insert a resistor R
f
between this pin and
V
CC
. The voltage is used for the current
limiter. The detection level is about 1/50
of the output current.
Output transistor ground pin.
Connect to ground together with pin 6.
