capacitor Cout flows. Hence, oscillation momentarily starts until the output of regulator V
out
rises high
enough even though
V
IN
is set less than Vhys. But Short-circuit protection circuit controls the rush current
less than Imax on fig.8. If this momentary oscillation is a problem in your applicaion, setting R
IN
less than
Vhys/Imax prevents oscillation.
In the S-87XXXXE series, the minimum operating voltage becomes 2.0 V as V
IN
voltage. If a drop in V
IN
voltage
occurs due to load current or rush current to be charged to the output capacitor when load current or the voltage
regulator is powered on at the time of release, set V
IN
to 2.0 V or more.
Also, in the S-87XXXXE Series, when sharply increasing only V
IN
pin voltage at 1 ms/V or less, with the SENSE pin
fixed to -V

-2V, a release pulse is output to the output pin of voltage detector. Be careful. In this
case, this release pulse is removed by setting the time constant of V
OR
pin 20ms or more with capacitance and pull-
up resistance. In addition, when the voltage of SENSE pin is fixed to between the detection voltage and the release
voltage at the detect condition, if sharply increasing only V
IN
pin voltage at 1 ms/V or less, the output of the detector
turns to the release condition. If this action is a problem in your system, please connect SENSE pin to V
IN
pin.

Shutdown Circuit (S-87XXXXC/E Series)
When V
PF
pin goes low (0.4 V or less) in the S-87XXXXC Series or at the time of voltage detection in the S-87XXXXE series,
current for the voltage regulator is shut down, with the current consumption (excluding the current which flows through the
pull-up resistor) lowered to 3.5
μ
A or less.
During shutdown, the M1 transistor in the voltage regulator shown in the Figure 6 is off and V
OUT
pin is pulled down by R1
and R2, whose value (R1+R2) is 5M
to 10M
. Input current of V
PF
pin is 0.1
μ
A or less.
Notes
The output voltage may not become 0 V if a load making I
OUT
under 50
μ
A is connected during shutdown..
DO NOT keep V
PF
pin floating state or in medium potential (between low and high levels). Otherwise a through-
type
current
occurs.
