· Output Capacitor
Ceramic Capacitor 2.2µF (Output voltage : 2.5~5.0V)
Ceramic Capacitor 4.7µF (Output voltage : 1.8~2.5V)
· Input Capacitor
Ceramic Capacitor 2.2µF
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.
It is possible to use a ceramic capacitor without ESR resistance for output.
The ceramic capacitor must be used more than 2.2µF or 4.7µF and B temperature characteristics.
3. The wire of VCC and GND is required to print full ground plane for noise and stability.
The input capacitor must be connected a distance of less than 1cm from input pin.
