Each input level is equivalent to LS-TTL. Therefore, it may be directly driven by an LS-TTL circuit. *5: A foldback type overcurrent protection circuit is built into the IC regulator. Therefore, avoid using it for the following applications as it may cause starting errors: (1) Constant current load (2) Plus/minus power (3) Series power (4) VO adjustment by raising ground voltage 43 GSI-3000J Series IExternal Dimensions 3.20.2 0.5 10.0 0.2 (unit:mm) 4.20.2 2.80.2 4.00.2 7.90.2 (17.9) a b 16.90.3 2.60.1 (2.0) a.

Variable output voltage with a single external resistor VIN 5 3 VO 25 VIN=VO+1V SI 15 0J + OPEN 2 47F SI-3000J 1 4 IREX REX V04 + 47F -3 GND GND 20 SI -3 12 0J Output Voltage VO (V) The output voltage may be increased by inserting resistor REX between terminals No.4 (sensing terminal) and No.3 (output terminal). 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-3000J 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.) 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=3000J series S: Stability coefficient of I4IN (may be set to any value) Output Voltage VO (V) 0J 12 -3 k SI X2=3 RE 15 J 90 5k -30 .2 SI X2=2 RE 0J k 05 .25 -3 SI X2=1 RE 10 5 0 1.0 External Resistor REX1 (k) 2.0 Note: In the SI-3000J 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-3000J series. 46 GSI-3000J Series ITypical Characteristics (Ta=25C) IO vs. VDIF Characteristics 1.0 Temperature Coefficient of Output Voltage(SI-3050J) 5.02 VIN=8V lO=0A Circuit Current(SI-3050J) 50 Dropout Voltage VDIF (V) Ground Current IG (mA) 0.8 40 Output Voltage VO (V) 0.6 30 5.00 0.4 20 lO=2A 1.5A 1A 0.2 10 0.5A 0A 0 0 0.5 1 1.5 2 4.98 -40 -20 0 20 40 60 80 100 120 140 0 0 5 10 15 Output Current IO (A) Ambient Temperature Ta (C) Input Voltage VIN (V) Quiescent Circuit Current(SI-3050J) 0.5 Output Voltage(SI-3050J) 6 Output Voltage(SI-3120J) 14 12 Quiescent Circuit Current Iqoff (mA) 0.4 5 Output Voltage VO (V) 0.3 VC=0V 4 lO=0A 0.5A 1A 1.5A 2A Output Voltage VO (V) 10 8 6 4 2 lO=0A 0.5A 1A 1.5A 2A 3 0.2 2 0.1 1 0 0 5 10 15 0 0 1 2 3 4 5 6 7 8 Input Voltage VIN (V) Input Voltage VIN (V) 0 0 5 10 15 20 Input Voltage VIN (V) Overcurrent Protection Characteristics(SI-3050J) 6 Overcurrent Protection Characteristics(SI-3120J) 14 12 Output Voltage VO (V) 4 Output Voltage VO (V) 12V 10V 15V 6V 10 8 6 4 2 0 0 2 1 0 0 1.0 2.0 3.0 4.0 1.0 2.0 3.0 18 3 V 22V 3V 1 15V 27V 25V 5 8V 4.0 Output Current IO (A) Output Current IO (A) ON/OFF Control Characteristics(SI-3050J) 6 VIN=8V lO=10mA 5 Thermal Protection(CharacteristicsSI-3050J) 6 VIN=8V lO=10mA 5 Output Voltage VO (V) 4 off 3 on 2 Output Voltage VO (V) 4 3 Note on Thermal Protection: 2 1 1 0 0 1.0 2.0 3.0 4.0 5.0 Output ON/OFF Control Voltage VC (V) 0 0 20 60 100 140 180 The thermal protection circuit is intended for protection against heat during instantaneous short-circuiting.
