An output-capacitor recommended the capacitor with more than 1.0µF and B type temperature characteristics. 2. The wire of VDD and GND is required to print full ground plane for noise and stability. 3. The input capacitor must be connected a distance of less than 1cm from input pin. 4. In case the output voltage is above the input voltage, the overcurrent flow by internal parasitic diode from output to input.
