C8051F41x devices include an on-chip low dropout voltage regulator (REG0). The input to REG0 at the
V
enabled, the output of REG0 appears on the V
power external devices. On reset, REG0 is enabled and can be disabled by software.
The input (V
tor (4.7 µF + 0.1 µF) to ground. This capacitor will eliminate power spikes and provide any immediate
power required by the microcontroller. A settling time associated with the voltage regulator is shown in
Table 8.1.
If the internal voltage regulator is not used, the V
