40kΩ
18
Regulated-voltage output pin (5V output)
19
VREG _{Connect a capacitor (about 0.1µF) between this pin and}
ground for stabilization.
VCC1

V_CC2 _{In applications that apply a voltage externally to the VCTL or}
TOC pin and use a fixed output duty, variations in the duty
can be suppressed by connecting this pin to V_CC1 (12 V).
VCC1
Voltage detection pin for low-voltage protection.
21
LVS _{To detect the supply voltage of 5 V or more, connect the}
zenor diode in series to set the detection voltage.
