Note:
1.
A 4.7 μF (±20%) or higher ceramic capacitor must be connected between V
DDIN
and the closest GND pin of
the device. This large decoupling capacitor is mandatory to reduce startup current, improving transient
response and noise rejection.
2. To ensure stability, an external 1 μF (±20%) output capacitor, C
DOUT
, must be connected between V
DDOUT
and
the closest GND pin of the device. Solid tantalum and multilayer ceramic capacitors are suitable as output
capacitors. A 100 nF bypass capacitor between V
DDOUT
and the closest GND pin of the device helps decrease
output noise and improves the load transient response.
