C ref : This device is necessary when it is required to enhance the ripple rejection or to delay the output start-up time(*1). (*1)Otherwise, it is not necessary. (Care must be taken since Cref may raise the gain, facilitating oscillation.) (*1)The output start-up time is proportional to Cre fX R 2. C IN, CO : Be sure to mount the devices CIN and CO as close to the device terminal as possible so as to prevent oscillation. The standard specification of CIN and CO is 0.33µF and 47µF, respectively. However, ajust them as necessary after checking. R 1, R2 : These devices are necessary to set the output voltage. The output voltage VO is given by the following formula: V O =V ref X (1+R2/R1) (Vref is 1.25V TYP) The standard value of R1 is 390Ω .But value up 10kΩ does not cause any trouble. -20 0 25 50 75 100 125 V IN-VO =5V 0.5V R 1=390Ω ,R2=2.7kΩ IOP :Output current when output voltage is 95% in comparison with the initial value Junction temperature Tj (˚C) Output peak current IOP (A) Load C ref 390Ω to10kΩR 1 R 2 C O V O D 1 C IN V IN

Low Power-Loss Voltage Regulators PQ30RV1/PQ30RV11/PQ30RV2/PQ30RV21 \ ON/OFF operation is available by mounting externally D2 and R3. \ When V ADJ is forcibly raised above Vref (1.25V TYP) by applying the external signal, the output is turned off (pass transistor of regulator is turned off). When the output is OFF, VADJ must be higher then Vref MAX., and at the same time must be lower than maximum rating 7V. In OFF-state, the load current flows to R L from VADJ through R2. Therefore the value of R2 must be as high as possible. \` V O '=V ADJ X R L/(RL+R 2) occurs at the load. OFF-state equivalent circuit R1 up to 10Ω is allowed. Select as high value of RL and R2 as possible in this range. In some case, as output voltage is getting lower (VO <1V) , impedance of load resistance rises. In such condition, it is sometime impossible to obtain the minimum value of VO '. So add the dummy resistance indicated by RD in the figure to the circuit parallel to the load. n ON/OFF Operation V C High : Output OFF Low : Output ON D 2 R 3R 1 R 2 C O V O R L V ADJ D 1 C IN V IN R 1 Equivalent Circuit in OFF-state R 2 R L D 2 V O ’ V ADJ R D n An Example of ON/OFF Circuit Using the 1-chip Microcomputer Output Port (PQ30RV1) <Specification> Output port of microcomputer V OH (max) =0.5 V V OH (min) =2.4 V (IOH =0.2mA) MAX. rating of IOH =0.5mA Output should be set as follows. 15.6V RL=52Ω (IO =0.3A) From V O =1.25V (1+R2/R1) we get VO =15.6V. R 2/R1=11.48 V ref(max)=1.3V we get R3=0 Ω If R1=10k Ω , we get R2=11.48 X R 1=114.8k Ω and IOH as follows, ingnoring RL (52 Ω ) : IOH =1.6V X (R1+R 2) /R1 X R 2 =1.6V X (10k Ω +114.8k Ω ) /10k Ω X 114.8k Ω =0.17mA Hence, IOH <0.2mA. Therefore VOH (min)is ensured. Next, assuming that VF(min) =0.5V for D2 in case of VOH (max), we get: IOH =(5V-0.5V) (R1+R 2) /R1 X R 2=0.49mA which is less than the rating. Figure 1 shows the VO -VC characteristics when R1=10k Ω , R2=115k Ω , R3=0 Ω , VIN=17V, RL=52 Ω , and D1=1S2076A (Hitachi).
