HIGH WITHSTAND-VOLTAGE VOLTAGE REGULATOR WITH RESET FUNCTION
S-87x Series
1. Reference voltage circuit
2. Voltage regulator
3. Short-circuit protection circuit
Operation
The reference voltage circuit operates all the time when the voltage is applied to VIN pin and is not
affected by the V
Figure 18 shows the voltage regulator circuit. The S-87x Series has a Pch MOS transistor as the output
control transistor.
Reverse current may break IC if V

V
The output voltage of the voltage regulator can be selected as follows:
2.5 V to 5.8 V ± 2.4 % (0.1 V step)
*1. Parasitic diode
Caution For an application with a load current of less than 1 μ A, the leakage current of the control
The S-87x Series has a built-in short-circuit protection circuit to protect the element from break caused by
a large current in case of a short circuit. The output short current is internally limited to approx. 70 mA.
Short-circuit protection circuit has three kinds characteristics according to input voltage (V
