Cin: Capacitor (39µF) for oscillation prevention
CO1: Output capacitor (39µF)
CO2: Output capacitor (39µF)
Tantalum capacitors are recommended particularly for low
temperatures (tantalum capacitors of about 0.47µ F in parallel).
D1, D2: Protection diodes.
Required for protection against reverse biasing between input
and output (Recommended diode: SANKEN EU2Z).

Notes:
*2: Refer to Dropout Voltage.
*3: Since PD(max) = (VIN–VO1) • IO1+ (VIN2–VO2) • IO2 + (VIN• Iq) = 22W, VIN(max), IO1(max) and IO2(max) may be limited
depending on operating conditions.
*4: The RESET terminal is pulled up in the IC; may be directly connected to logic circuits.
*6: The thermal protection function is built in VO1 (CH1 side) only. The design thermal protection starting temperature is 151
°C (min.) and 165°C (typ). These values represent the design warranty.
