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

9
DRES Reset delay; connect a capacitor to ground for delay time
adjustment.
10
SRES 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
V_Q
5-V output voltage; block to ground with 22-µF capacitor,
ESR < 3 Ω.
18
V_I
Input voltage; block to ground directly on the IC with ceramic
capacitor.
