RO

Reset output; the open collector output is connected to the

5-V output via an integrated resistor of 30 kΩ.

Ground

9

D

Reset 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.
