Selection of Capacitor
Set 1
μF or more value bypass capacitor C1 between VIN pin and GND pin as close as possible.
As for R1202xxxxA/B version Set 1.0
μF – 4.7μF capacitor C2 between VOUT pin and GND pin.
As for R1202xxxxD version, set 0.22
μF – 1.0μF capacitor C2 between VOUT pin and GND pin.
External Components Setting
If the spike noise of VOUT may be large for R1202xxxxA/B, the spike noise may be picked into VFB pin and make
the operation unstable. In this case, use a R3 of the resistance value in the range from 1k
Ω to 5kΩ to reduce a
noise level of VFB.
