· Output capacitor
· Input Capacitor
· Note
1. The output capacitor is required between output and GND to prevent oscillation.
2. The ESR of capacitor must be defi ned in ESR stability area.
3. The wire of V
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 fl ow by internal parastic diode from
It is possible to use a ceramic capacitor without ESR resistance for output.
The ceramic capacitor must be used more than 1.0µF and B temperature characteristics.
