The output capacitor is required between output and GND to prevent oscillation. 2. The ESR of capacitor must be defined in ESR stability area. It is possible to use a ceramic capacitor without ESR resistance for output. The ceramic capacitor must be used more than 1.0µF and B type (X5R) 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. The rise time will chage depending on the capacitance value. 6. 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. *Temperature Characteristics: B Type (X5R Type)
