Tantalum capacitors are recommended, 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.
