Note: 1. A 4.7 μF (±20%) or higher ceramic
capacitor must be connected between VDDIN and the closest GND pin of the device.
This large decoupling capacitor is mandatory to reduce startup current, improving transient
response and noise rejection.
Note: 2. To ensure stability, an external 1 μF (±20%) output capacitor, CDOUT, must
be connected between VDDOUT 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 VDDOUT and the closest GND pin of the device helps
decrease output noise and improves the load transient response.

Notes:
- 1.It is recommended to enable the
Supply Monitor (see Table 59-9 Threshold Selection).
- 2.The Supply Monitor operates down to 1.7V.
- 3.Once the Supply Monitor threshold is
reached, it takes <200 µs to generate the internal reset of the device. The
internal reset will remain active all the way until the POR becomes active.
- 4.The 200 us reset time parameter is
for design guidance only and is not tested in manufacturing.
