Note 1. The output capacitor is required between output and GND to prevent oscillation. 2. The ESR of capacitor must be defined in ESR stability 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 a distance of less than 1cm from input pin. 5. The capacitor is connected to Cn mus.
