Each input level is equivalent to LS-TTL. Therefore, it may be directly driven by an LS-TTL circuit. *6: When setting output voltage to 5V or less, input voltage needs to be set to 6V or over to operate stably. *7: A foldback type overcurrent protection circuit is built into the IC regulator.

Tantalum capacitors are recommended for C1 and C0, particularly at low temperatures. : Protection diode This diode is required for protection against reverse biasing of the input and output. Sanken EU2Z is recommended. : External resistor for setting output voltage Relationship between output voltage VO and external resistors R1 and R2 is as follows. R1 VO=VREF* 1+ (VREF=2.55V(typ.))

The current IREX flowing into terminal No.4 is 1mA (typ.), therefore the adjusted output voltage VOUT is: VO=V04+IREX*REX *V04: output voltage of SI-3000F 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. 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.) 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-3000F series S: Stability coefficient of I4IN (may be set to any value) 25 Output Voltage VO (V) 20 15 F 150 SI-X3=3.75k E2 R F 120 SI-32=3k X RE 90F I-30 2.25k S X2= RE 0F 305 5k SI- X2=1.2 10 RE 5 0 1.0 2.0 External Resistor REX1 (k) Note: In the SI-3000F 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-3000F series. 37 qSI-3000F Series sTypical Characteristics (Ta=25C) IO vs. VDIF Characteristics 0.6 Temperature Coefficient of Output Voltage(SI-3050F) 5.06 5.04 VIN=8V IO =0A VO =5V Output ON/OFF Control(SI-3050F) 6 0.5 5 Dropout Voltage VDIF (V) Output Voltage VO (V) 0.4 5.02 Output Voltage VO (V) 4 0.3 5.00 3 VIN=8V IO =10mA 2 0.2 4.98 0.1 4.96 4.94 -40 -20 1 0 0 0.2 0.4 0.6 0.8 1.0 0 20 40 60 80 100 120 140 0 0 1.0 2.0 3.0 4.0 Output Current IO (A) Ambient Temperature Ta (C) Output ON/OFF Control Voltage Vc (V) Rise Characteristics(SI-3050F) 6 Rise Characteristics(SI-3120F) 14 12 Overcurrent Protection Characteristics(SI-3050F) 6 5 5 Output Voltage VO (V) Output Voltage VO (V) =0 10 8 6 4 2 0 0 IO=0A =0.5A =1.0A Output Voltage VO (V) 8V 10V 4 6V VI N= 1. 3 0.5A 0.75A 3 2 2 1 1 0 0 1 2 3 4 5 6 2 4 6 8 10 12 14 16 0 0 Input Voltage VIN (V) Input Voltage VIN (V) 0.2 0.4 0.6 0.8 1.0 1.2 15 1.4 1.6 140 180 Output Current IO (A) Overcurrent Protection Characteristics(SI-3120F) 14 12 Overcurrent Protection Characteristics(SI-3140F) 30 VIN=27V 25 30 40V 35V 15 Thermal Protection Characteristics(SI-3050F) 6 25 5 Output Voltage VO (V) Output Voltage VO (V) 10 15 V 3V VIN =1 22 V 20 Output Voltage VO (V) 4 VIN=8V IO=10mA 3 8 6 4 2 0 18V 10 2 5 1 0 0.5 1.0 1.5 2.0 0 0 0.5 1 1.5 2 2.5 3 0 0 20 60 100 Output Current IO (A) Output Current IO (A) Case Temperature Tc (C) Note on Thermal Protection: The thermal protection circuit is intended for protection against heat during instantaneous short-circuiting.
