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 internal resistor (between terminals No. 4 and No.1) is a semiconductor resistor, which has approximately thermal characteristics of +0.2%/°C. It is important to keep the thermal characteristics in mind when adjusting the output voltage. 2.

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 *V04: Output voltage of SI-3000C series S: Stability coefficient of I4IN (may be set to any value) 25 Output Voltage VO (V) 20 C 150 Ω SI-X3=3.75k 2 RE C 120 SI-3 3kΩ 15 C 090 5kΩ SI-32=2.2 X RE REX 2= 0C 305 5kΩ SI- X2=1.2 10 RE 5 33C SI-301.9kΩ REX2= 0 1.0 2.0 External Resistor REX1 (kΩ) Note: In the SI-3000C series, the output voltage increase can be adjusted as mentioned above. 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. 40 GSI-3000C Series ITypical Characteristics (Ta=25°C) IO vs. VDIF Characteristics 0.8 Temperature Coefficient of Output Voltage(SI-3050C) 5.08 VIN=8V lO=0A VO=5V Circuit Current(SI-3050C) 50 VO=5V 5.06 Dropout Voltage VDIF (V) Output Voltage VO (V) 5.04 Ground Current lG (mA) 0.6 40 30 0.4 5.02 20 IO=1.5A 5.00 0.2 4.98 0 0 10 1.0A 0.5A 0A 0.5 1.0 1.5 4.96 –40 –20 0 20 40 60 80 100 120 140 0 0 2 4 6 8 10 Output Current lO (A) Ambient Temperature Ta (°C) Input Voltage VIN (V) Output Voltage(SI-3033C) 5 Output Voltage(SI-3050C) 7 6 Output Voltage(SI-3240C) 30 Output Voltage VO (V) 4 25 Output Voltage VO (V) 0.5A 3 A =0 5 4 3 0.5A 2 1 0 1A lO A =0 Output Voltage VO (V) 20 lO=0A 0.5A 1A 1.5A 2 1. 5A lO 1A 1. 5A 15 10 1 5 0 0 1 2 3 4 5 6 0 1 2 3 4 5 6 7 Input Voltage VIN (V) Input Voltage VIN (V) 0 0 10 20 30 40 Input Voltage VIN (V) Overcurrent Protection Characteristics(SI-3033C) 5 Overcurrent ProtectionCharacteristics(SI-3050C) 6 Overcurrent Protection Characteristics(SI-3240C) 25 VIN=40V 6V 4 5 20 8V VIN=30V Output Voltage VO (V) Output Voltage VO (V) Output Voltage VO (V) V 35V 27V 3 8V 15 3 2 5V 6V 10 2 1 1 5 0 0 0.5 1.0 1.5 2.0 2.5 3.0 0 0 1.0 2.0 3.0 4.0 0 0 1.0 25 V 4 2.0 30V 15 15V Output Current IO (A) ON/OFF Control Characteristics(SI-3050C) 6 VIN=8V lO=1A 5 Output Voltage VO (V) Output Voltage VO (V) VIN =4. 5V 3.0 4.0 Output Current lO (A) Output Current lO (A) Thermal ProtectionCharacteristics(SI-3050C) 6 5 VIN=8V lO=10mA 4 4 off 3 3 2 on 2 Note on Thermal Protection: The thermal protection circuit is intended for protection against heat during instantaneous short-circuiting.
