The output capacitor is required between output and GND to prevent oscillation. 2. Use a capacitance that is within the ESR characteristics stable range for output capacity. * It is possible to use a ceramic capacitor without ESR resistance for output. The ceramic capacitor must be used more than 2.2F and B type temperature characteristics. 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 a distance of less than 1cm from input pin. 5. The capacitor is connected to Cn must have low leakage current characteristics, because Cn pin is high impedance. 6. The 6pin (heat sink pin) must be connected to GND. This pin can be only connected to GND. 7. In case the output voltage is above the input voltage, the overcurrent flow by internal parasitic diode from output to input. In such application, the external bypass diode must be connected between output and input pin.
