Note
1. The output capacitor is required between output and GND to prevent oscillation.
2. The output capacitor must be used in ESR stable area.
3. The wire of VCC and GND is required to print full ground plane for noise and stability.
4. The input capacitor must be connected in 1cm from input pin.
5. The capacitor connected to Cn must have low leakage current characteristics,
because Cn pin is high impedance.
6. In case the output voltage is above the input voltage, the overcurrent flows by internal parasitic
diode from output to input. In such application, the external bypass diode must be connected
between the output pin and the input pin.

Power Dissipation
Land Pattern Recommendation
This IC's GND pin and the Heat Spreader Bottom effectively radiate heat. By increasing these copper foil
pattern area of PCB, power dissipation improves. Please kindly design PCB pattern taking care of above
features about the power dissipation.
