8. Voltage Regulator
The CP2102 includes an on-chip 5 to 3 V voltage regulator. This allows the CP2102 to be configured as either a
USB bus-powered device or a USB self-powered device. These configurations are shown in Figure 6 and Figure 7.
When enabled, the 3 V voltage regulator output appears on the V
devices. See Table 10 for the voltage regulator electrical characteristics.
Alternatively, if 3 V power is supplied to the V
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 8.
The USB max power and power attributes descriptor must match the device power usage and configuration. See
application note “AN144: CP210x Customization Guide” for information on how to customize USB descriptors for
the CP2102.
Note: It is recommended that additional decoupling capacitance (e.g., 0.1 µF in parallel with 1.0 µF) be provided on the REGIN
