The current IREX flowing into terminal No.4 is 1mA (typ.)(SI-3033C:0.43mA (typ.)), therefore the adjusted output voltage VOUT is: VO=V04+IREX•REX *V04: output voltage of SI-3000C series However, the built-in resistor (between terminals No. 4 and No.1) is a semiconductor resistor, which has approximately thermal characteristics of +0.2%/°C.

However, when the rise is set to approximately 10V compared to output voltage V04, the necessary output current may not be obtained due to the S.O.A. protection circuit in the SI-3000C series. 25 Output Voltage VO (V) The output voltage may be increased by inserting resistors REX1 between terminals No.4 (sensing terminal) and No.3 (output terminal) and REX2 between terminals No.4 and No.1 (ground terminal). The current I4IN flowing into terminal No.4 is 1mA (typ.)(SI-3033C: 0.43mA(typ.)) so the thermal characteristics may be improved compared to the method shown in 1 by setting the external current IREX1 at approximately 5 times the value of I4IN (stability coefficient S=5). The adjusted output voltage VOUT in this case is: VO=V04+REX1•IREX1 IREX1=S•I4IN The value of the external resistors may be obtained as follows: VO-V04 V04 REX1= REX2= S•I4IN , (S-1)•I4IN 44 C 240 SI-3 30 C 150 Ω SI-X32=3.75k RE C 120 SI-3 3kΩ 20 2= REX C 090 5kΩ SI-3X2=2.2 15 RE 0C 305 5kΩ SI- X2=1.2 RE 10 3C SI-3013.9kΩ 5 0 REX2= 1.0 External Resistor REX1 (kΩ) 2.0 ●SI-3000C Series ■Typical Characteristics (Ta=25°C) IO vs. VDIF Characteristics Temperature Coefficient of Output Voltage(SI-3050C) 0.8 Circuit Current(SI-3050C) 5.08 50 VO=5V VIN=8V lO=0A VO=5V 5.02 5.00 4.98 1.0 1.5 4.96 –40 –20 Output Current lO (A) Rise Characteristics(SI-3033C) 0A 0 20 40 60 0 0 80 100 120 140 30 6 25 1A 1 A =0 lO 3 1A 2 0 1 2 3 4 5 6 Overcurrent Protection Characteristics(SI-3033C) 10 0 1 2 3 4 5 6 0 0 7 Overcurrent ProtectionCharacteristics(SI-3050C) 1 4 V 15 6V 8V 20 3 2 0.5 1.0 1.5 2.0 2.5 0 0 3.0 1.0 2.0 3.0 4.0 Output Current lO (A) Output Current IO (A) ON/OFF Control Characteristics(SI-3050C) 40 27V 15 10 5 1 0 30 Overcurrent Protection Characteristics(SI-3240C) Output Voltage VO (V) 5V =4. 5V 6V 2 VIN=30V Output Voltage VO (V) 15V VIN 8V 20 25 5 3 10 Input Voltage VIN (V) 6 4 10 lO=0A 0.5A 1A 1.5A 15 Input Voltage VIN (V) 5 8 5 Input Voltage VIN (V) Output Voltage VO (V) 5A 1. 0.5A 6 20 1 0 0 0 Output Voltage VO (V) Output Voltage VO (V) A =0 lO Output Voltage VO (V) 5A 1. 5 4 4 Rise Characteristics(SI-3240C) 7 4 3 2 Input Voltage VIN (V) Rise Characteristics(SI-3050C) 0.5A 1.0A 0.5A 10 Ambient Temperature Ta (°C) 5 2 IO=1.5A 30V 0.5 20 35V 0 0 30 VIN=40V 0.2 5.04 25 V 0.4 40 Ground Current lG (mA) Output Voltage VO (V) Dropout Voltage VDIF (V) 5.06 0.6 0 0 1.0 2.0 3.0 4.0 Output Current lO (A) Thermal ProtectionCharacteristics(SI-3050C) 6 6 VIN=8V lO=1A 5 4 Output Voltage VO (V) Output Voltage VO (V) 5 off 3 on 2 3 2 Note on Thermal Protection: The thermal protection circuit is intended for pro- 1 1 0 0 VIN=8V lO=10mA 4 1.0 2.0 3.0 Output ON/OFF Control Voltage (V) 4.0 0 20 tection against heat during instantaneous shortcircuiting.
