2. Power-on reset circuit
The Nch open-drain output products of the S-807 Series can be used to construct a power-on reset circuit. Following is an

Note 1: R should be 7.5k
or less for purpose of protection against oscillation.
Note 2:
“

momentarily discharges the charge received via
“

”
at the falling edge of power off. There
is no need to insert a diode, when there is no conflict with application circuit even if there is a
delay in the falling edge of OUT at the falling edge of power off.
Note 3: When there is a sharp rise in power, the output voltage may go
“

”
momentarily in unstable range of
the output voltage (the output voltage is unstable below the minimum operating voltage) .
