Pin function

• Output pin 1

• Output pin 2

• Output pin 3

25

VM

• Power supply pin that provides the

output

26

RF

• Output current detection

Connect the resistor Rf between this pin

and ground.

• The current limiter limits the output

current to the value set by VRF/Rf

(current limiter operation).

Equivalent circuit

5

C

• The capacitor connected to this pin

determines both the time the output is

turned off when the current limiter

operates and the time the output current

is ignored.

6

R

• The resistor connected to this pin

determines the charge current for the pin

C capacitor.
