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.) TTSD 5 C Notes: *1. Since PD(max) = (VIN - VO) * IO1+ (VIN -VO2) * IO2 = 22 (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 = 0.04A or IO2 = 0.1A) 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. 12 SI-3102S Electrical Characteristics s Line Regulation (1) 5.10 VIN = VC IO2 = 5mA s Line Regulation (2) 5.10 VIN = VC IO1 = 5mA s Load Regulation (1) 5.10 VIN = VC 5.05 Output voltage VO (V) Output voltage VO (V) 5.05 Output voltage VO (V) 5.05 IO2 = 0A 50mA 100mA VIN = 6V 14V 30V 5.00 IO1 = 0A 20mA 40mA 5.00 5.00 4.95 4.95 4.95 4.90 4.90 4.90 4.85 0 5 10 15 20 25 30 35 Input voltage V IN (V) 4.85 0 5 10 15 20 25 30 35 Input voltage VIN (V) 4.85 0 10 20 30 40 50 Output current IO (mA) s Load Regulation (2) 5.10 VIN = VC s Rise Characteristics 6 5 VIN = 6V,14V s Quiescent Circuit Current 12 VC = 0V IO1 = 0A 4 3 2 1 0 IO1 = 0A 20mA 40mA Quiescent current lq (mA) 5.05 Output voltage VO (V) Output voltage VO (V) 10 8 6 4 2 0 0 1 2 3 4 5 6 7 0 5 10 15 20 25 30 35 Input voltage VIN (V) Input voltage VIN (V) 5.00 4.95 30V 4.90 4.85 0 20 40 60 80 100 Output current IO (mA) s ON/OFF Control Characteristics 6 VIN = 14V IO2 = 5mA s Overcurrent Protection Characteristics (1) 6 VIN = VC IO2 = 5mA s Overcurrent Protection Characteristics (2) 6 VIN = VC IO1 = 5mA 5 Output voltage VO2 (V) Output voltage VO1 (V) 5 4 3 2 1 0 0 1 2 3 4 5 6 0 20 40 60 80 100 120 Output ON/OFF control voltage VC (V) Output current IO (mA) Output voltage VO2 (V) 5 4 3 2 1 0 0 0.1 0.2 0.3 0.4 0.5 Output current IO2 (A) 4 OFF 3 2 1 0 ON VIN = 6V 14V 30V VIN = 6V 14V 30V s Thermal Protection Characteristics 6 VIN = 6V IO1 = IO2 = 5mA s Overvoltage Protection Characteristics 6 VIN = VC IO2 = 5mA s Ta--PD Characteristics 25 With infinite heatsink With silicone grease G746 (Shin-Etsu Chemical) Heatsink: aluminum 5 Output voltage VO1 (V) 5 Power Dissipation PD (W) Output voltage VO (V) VO1 20 200 * 200 * 2mm (2.3C/W) 4 3 2 1 0 100 4 3 VO2 15 100 * 100 * 2mm (5.2C/W) 10 75 * 75 * 2mm (7.6C/W) 2 1 0 26 5 Without heatsink 120 140 180 200 220 240 28 30 32 34 36 38 0 -40 -20 0 20 40 60 80 100 120 140 160 Ambient temperature Ta (C) Note on Thermal Protection Characteristics: The thermal protection circuit is intended for protection against heat during instantaneous short-circuiting.
