APPLICATION CIRCUITS • VOLTAGE BOOST CIRCUIT The output voltage can be obtained by the following formula : VIN VIN R×5RL SERIES VOUT VOUT Since the quiescent current of R × 5RE Series is so + GND C2 R1 small that the resistances of R1 and R2 can be set as ISS + 1 VOUT=Vreg* · (1+R2/R1) + ISS R · 2 large as several hundreds kΩ and therefore the sup- C1 ply current of “Voltage Boost Circuit” itself can be 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 supply circuit can be constructed by using two R × 5RL IC1 VIN VIN R×5RL20A VOUT C1 VOUT1 5V + This circuit diagram shows a dual power supply D ISS GND circuit with an output of 3V and an output of 5V.
