ABSOLUTE MAXIMUM RATINGS Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the permanent damages and may degrade the life time and safety for both device and system using the device in the field. The functional operation at or over these absolute maximum ratings is not assured. RECOMMENDED OPERATING CONDITIONS (ELECTRICAL CHARACTERISTICS) All of electronic equipment should be designed that the mounted semiconductor devices operate within the recommended operating conditions. The semiconductor devices cannot operate normally over the recommended operating conditions, even if when they are used over such conditions by momentary electronic noise or surge. And the semiconductor devices may receive serious damage when they continue to operate over the recommended operating conditions. 4 Rx5RL ELECTRICAL CHARACTERISTICS * Rx5RL20A Symbol Topt=25C Item Conditions VIN=4.0V VOUT Output Voltage IOUT Output Current VIN=4.0V VOUT Load Regulation VIN=4.0V IOUT VDIF ISS VOUT VIN VIN VOUT Topt 10AIOUT10mA Min.

However, when the VIN VIN C1 + Rx5RL SERIES VOUT wire connected to Vin is long, use Capacitor C1. Output VOUT + noise can be reduced by using Capacitor C2. C2 GND Insert Capacitors C1 and C2 with the capacitance of 0.1F to 2.0F between Input/Output Pins and GND Pin GND GND with minimum wiring. APPLICATION CIRCUITS * VOLTAGE BOOST CIRCUIT The output voltage can be obtained by the following formula : VIN VIN Rx5RL SERIES VOUT VOUT Since the quiescent current of Rx5RE 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 k and therefore the sup- C1 ply current of "Voltage Boost Circuit" itself can be R2 reduced. Furthermore, since Rx5RL 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 Rx5RL Series. * DUAL POWER SUPPLY CIRCUIT As shown in the circuit diagram, a dual power supIC1 ply circuit can be constructed by using two Rx5RL VOUT VIN VIN VOUT1 5V Rx5RL20A C1 + This circuit diagram shows a dual power supply D ISS GND circuit with an output of 3V and an output of 5V. IC2 VOUT VIN VOUT2 3V Rx5RL30A C2 + C3 + R 16 When the minimum output current of IC2 is larger than ISS of IC1, Resistor R is unnecessary. Diode D is a protection diode for the case where VOUT2 becomes GND GND Series. GND larger than VOUT1. Rx5RL * CURRENT BOOST CIRCUIT Output current of 60mA or more can be obtained by Tr.1 the current boost circuit constructed as shown in this cirVIN VIN C1 cuit diagram. VOUT Rx5RL SERIES VOUT + + GND C2 GND GND * CURRENT BOOST CIRCUIT WITH OVERCURRENT LIMIT CIRCUIT A circuit for protecting Tr.1 from the destruction R2 Tr.1 caused by output short-circuit or overcurrent is shown in Vbe2 this circuit diagram. Tr.2 IOUT VIN VIN C1 + R1 Rx5RL SERIES VOUT + VOUT C2 GND When the voltage reduction caused by the current ( aa IOUT) which flows through R2 reaches Vbe2 of Tr.2 by additionally providing the current boost circuit with Tr.2 and R2, Tr.2 is turned on and the base current of Tr.1 is GND GND increased, so that the output current is limited. Current limit of overcurrent limit circuit is obtained as follows : IOUT Vbe2/R2 * CURRENT SOURCE A current source with the structure as shown in this IOUT VIN VIN C1 + Rx5RL SERIES GND VOUT R ISS circuit diagram can be used. Output Current IOUT is obtained as follows : 1 IOUT= Vreg* /R + ISS Output current, IOUT should not exceed its allowable current. *1) Vreg : Set output voltage of Rx5RL Series. 17 1.
