HIGH WITHSTAND-VOLTAGE VOLTAGE REGULATOR WITH RESET FUNCTION Rev.7.2_00 S-87x Series Seiko Instruments Inc. 29 4. Delay circuit The delay circuit outputs voltage detector output (VOR) with delay after the voltage at VIN pin has become release voltage (+VDET) at the rising of VIN pin. In Figure 22, when Vcd exceeds the reference voltage (Vref), the output voltage pin detection voltage output (VOR) changes from low to high level, providing delay output. When the voltage at VIN pin falls under the detection voltage (−VDET), the N2 transistor turns ON, therefore the charge of the external capacitor (CD) is rapidly discharged and the voltage detector output (VOR) changes from high to low level without delay. The external capacitor (CD) is charged with constant current, and is practically independent of VIN voltage. Its delay time (tpd) is expressed by the following equation: VOR Vcd CD Vref IC CD Figure 22 Caution 1. Unless an output delay is needed, keep CD pin open. Do not apply external voltage other than ground potential to CD pin, which may cause IC breakdown. 2. When designing your printed-circuit board layout, take care that no leakage current flows to the external capacitor (C D), otherwise the correct delay time may not be obtained. Because the value of the constant current source (I C) is only 195 nA, C D to impedance is high.

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 R1 and R2, whose value (R1+R2) is 5 MΩ to 10 MΩ. Input current of VPF pin is 0.1 μA or less. Caution 1. The output voltage may not become 0 V when the load which makes IOUT under 1 μA 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.
