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.µF or and B 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. In case the output voltage is above the input voltage, the overcurrent flow by internal parastic diode from output to input.
