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. * Any products mentioned in this catalog are subject to any modification in their appearance and others for improvements without prior notification. * The details listed here are not a guarantee of the individual products at the time of ordering.
