7. Output Section
Because the output terminal (pin 9) carries a large current, the collector and emitter of the output transistor are brought out to
the VH and VL terminals. In principle, VH is connected to VCC and VL is connected to GND, but VH can be supplied from another
power supply (4 to 18 V). Note that VL and GND should be connected as close to the IC package as possible. A capacitor of
0.1 µF or more is inserted between VH and VL (see Figure 9).
