s PIN DESCRIPTION
TO-220 Symbol Description
1
Supply Supply voltage. Nominally 5 V to 40 V.
2
Output Output pin. Current flows from supply through the load into the pin. Nominal current is 8 mA to 2 A.
3
GND Ground supply.
diode are bonded to a separate pin.
4
Error Error indicating pin. Sinks current to ground if the protection and/or detection circuitry is activated.
Note: the current must be externally limited to 8 mA.
5
Input TTL compatible input. A LOW input signal turns the output transistor off and a HIGH input turns it on.
