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 1F 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.
