3ROReset output; the open collector output is connected to the
5-V output via an integrated resistor of 30 kΩ.

GND Ground
9DReset delay; connect a capacitor to ground for delay time
adjustment.
10 RADJ Reset switching threshold; for setting the switching threshold,
output to ground with voltage divider. If this input is connected
to ground, the reset is triggered at an output voltage of 4.5 V.
11 W Watchdog input; positive-edge-triggered input for monitoring a
microcontroller.
12 Q 5-V output voltage; block to ground with 22 µF capacitor,
ESR < 3 Ω.
18 I Input voltage; block to ground directly on the IC with ceramic
capacitor.
