Tantalum capacitors are recommended for CO1, CO2 and CIN, especially at low temperatures. *2 D1, D2, D3 : Protection diode. Required as protection against reverse biasing between input and output. (Recommended diode: Sanken EU2Z.) Notes: *1. Since PD(max) = (VIN - VO) * IO1+ (VIN -VO2) * IO2 = 18 (W), VIN (max), IO1(max) and IO2 (max) may be limited depending on operating conditions. Refer to the Ta--PD curve to compute the corresponding values. *2. Refer to the dropout voltage. *3. IS1 rating shall be the point at which the output voltage VO1 or VO2 (VIN = 14V, IO1 = 0.05A or IO2 = 0.3A) drops to -5%. *4. Overvoltage protection circuit is built only in CH2 (VO2 side). *5. The indicated temperatures are junction temperatures. *6. All terminals, except VIN and GND, are open. 10 SI-3101S Electrical Characteristics s Line Regulation (1) 5.1 VC = 5 (V) IO2 = 0 (A) Output voltage VO (V) Output voltage VO (V) s Line Regulation (2) 5.1 VC = 5 (V) I O1 = 0 (A) s Load Regulation (1) 5.1 VC = 5 (V) I O2 = 0 (A) Output voltage VO (V) IO1= 0mA 50mA I O2 = 0A 0.3A 5.0 V IN = 6V 14V 5.0 22V 5.0 70mA 0.5A 4.9 0 0 5 10 15 20 25 4.9 0 0 5 10 15 20 25 4.9 0 0 10 20 30 40 50 60 70 Input voltage VIN (V) Input voltage V IN (V) Output current IO (mA) s Load Regulation (2) 5.1 VC = 5 (V) I O1 = 0 (A) Output voltage VO (V) s Rise Characteristics 6 s Quiescent Circuit Current 10 I O1 = 0 (A) Vc = 0 (V) 5 4 3 2 1 Output voltage VO (V) V IN = 6V,14V Load resistor 100 5.0 22V 71.4 Quiescent current lq (mA) 5 4.9 0 0 0.1 0.2 0.3 0.4 0.5 0.6 0 0 2 4 6 8 10 0 0 5 10 15 20 Output current IO (A) Input voltage VIN (V) Input voltage VIN (V) s ON/OFF Control Characteristics 6 5 Output voltage VO2 (V) s Overcurrent Protection Characteristics (1) 6 5 Output voltage VO1 (V) s Overcurrent Protection Characteristics (2) 6 5 Output voltage VO2 (V) 4 3 2 V IN = 14V, 22V 4 3 2 1 0 IO2 = 0 (A) VC = 5 (V) V IN = 6V 14V 22V 4.5V VIN = 6V 14V 22V 4 3 2 1 0 6V 4.5V I O1 = 0 (A) VC = 5 (V) OFF 1 0 0 1 2 3 4 ON 5 6 0 0.05 0.1 0.15 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 Output ON/OFF control voltage VC (V) Output current IO (A) Output current IO (A) s Thermal Protection Characteristics 6 5 Output voltage VO1 (V) s Overvoltage Protection Characteristics 6 s Ta--PD Characteristics 20 With infinite heatsink With silicone grease G746 (Shin-Etsu Chemical) Heatsink: aluminum VIN = 6 (V) I O1 = I O2 = 5 (mA) 5 Power Dissipation PD (W) Output voltage VO (V) 4 3 2 1 0 0 130 140 150 160 Ambient temperature Ta (C) 4 3 2 1 IO1 = I O2 = 5 (mA) VC = 5 (V) VO1 VO2 15 200 * 200 * 2mm (2.3C/W) 10 100 * 100 * 2mm (5.2C/W) 75 * 75 * 2mm (7.6C/W) 5 Without heatsink 0 10 20 30 40 0 --30 --20 0 20 40 60 80 100 115 Input voltage VIN (V) Operating temperature Ta (C) Note on Thermal Protection Characteristics: The thermal protection circuit is intended for protection against heat during instantaneous short-circuiting.
