*Temperature Characteristics:
Note
1. The output capacitor is required between output and GND to prevent oscillation.
2. The output capacitor must be used in ESR stable area.
It is possible to use a ceramic capacitor without ESR resistance for output.
The ceramic capacitor must be more than 1µF with 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 in 1cm from input pin.
5. When the output voltage oversteps the input voltage, the overcurrent can flow by internal parasitic
diode. In such application, the external bypass diode must be connected
between output and input pin.
