HIGH WITHSTAND-VOLTAGE VOLTAGE REGULATOR WITH RESET FUNCTION
S-87x Series
6. Shutdown circuit (C/E/G type)
When VPF pin goes low (0.4 V or less) in the C/G type or at the time of voltage detection in the E type
current for the voltage regulator is shut down, the current consumption (excluding the current which flows
through the pull-up resistor) lowers to 3.5 μA or less.
During shutdown, the M1 transistor in the voltage regulator shown in the Figure 17 is off and VOUT pin is
pulled down by R
