9. Voltage Regulator
The CP2101 includes an on-chip 5-to-3 V voltage regulator. This allows the CP2101 to be configured as
either a USB bus-powered device or a USB self-powered device. These configurations are shown in
Figure 9.1 and Figure 9.2. When enabled, the 3 V voltage regulator output appears on the VDD pin and can
be used to power external 3V devices. See Table 9.1 for the voltage regulator electrical characteristics.
Alternatively, if 3 V power is supplied to the VDD pin, the CP2101 can function as a USB self-powered
device with the voltage regulator disabled. For this configuration, it is recommended that the REGIN input
be tied to the 3 V net to disable the voltage regulator. This configuration is shown in Figure 9.3.
The USB max power and power attributes descriptor must match the device power usage and configura-
tion. See application note “AN144: CP2101 Customization Guide” for information on how to customize USB
descriptors for the CP2101.
Note:
It is recommended that additional decoupling capacitance (e.g., 0.1 F in parallel with 1.0 F) be pro-
vided on the REGIN input.
