Insert Capacitors C1 and C2 with the capacitance of 0.1µF to 2.0µF between Input/Output Pins and GND Pin with minimum wiring. GND GND APPLICATION CIRCUITS • VOLTAGE BOOST CIRCUIT The output voltage can be obtained by the following formula : VIN VIN R×5RL SERIES GND + C1 ISS VOUT VOUT *1 VOUT=Vreg · (1+R2/R1) + ISS R · 2 Since the quiescent current of R × 5RE Series is so small that the resistances of R1 and R2 can be set as large as several hundreds kΩ and therefore the supply current of “Voltage Boost Circuit” itself can be + C2 R1 R2 reduced. Furthermore, since R × 5RL Series are operated by a constant voltage, the supply current of “Voltage Boost Circuit” is not substantially affected by the input voltage. *1) Vreg : Set Output Voltage of R×5RL Series. • DUAL POWER SUPPLY CIRCUIT As shown in the circuit diagram, a dual power supIC1 VIN VIN R×5RL20A GND IC2 VIN C2 GND + GND GND R×5RL30A VOUT C3 + R VOUT2 3V VOUT C1 + D ISS VOUT1 5V ply circuit can be constructed by using two R × 5RL Series.
