Reference voltage circuit The reference voltage circuit operates all the time when the voltage is applied to VIN pin and is not affected by the VPF signal. 2. Voltage regulator 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 VOUT potential is higher than VIN, because a parasitic diode is formed between VIN and VOUT due to the structure of the control transistor. Therefore, keep VOUT lower than VIN+0.3 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) VIN VREF − M1 *1 + VOUT R1 R2 *1. Parasitic diode Figure 18 Voltage regulator circuit Caution For an application with a load current of less than 1 μA, the leakage current of the control transistor M1 increases the output voltage. 3. Short-circuit protection circuit 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 (VIN) as shown in Figure 19 to 21. At 5 V Output: (a) VIN/VOUT≥2.0 (b) 1.5≤VIN/VOUT
