HIGH WITHSTAND-VOLTAGE VOLTAGE REGULATOR WITH RESET FUNCTION

S-87x Series

Rev.8.0_02

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

A 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 R1 and R2, whose value (R1R2) is 5 M to 10 M. Input current of VPF pin is 0.1 A or

less.

Caution 1. The output voltage may not become 0 V when the load which makes IOUT under 1 A is

connected during shutdown.

2. DO NOT keep VPF pin floating state or medium potential (between low and high

levels). Otherwise through-type current flows.
