10. Voltage Regulator
The CP2110 includes an on-chip 5 to 3.45 V voltage regulator. This allows the CP2110 to be configured as either a
USB bus-powered device or a USB self-powered device. A typical connection diagram of the device in a bus-
powered application using the regulator is shown in Figure 11. When enabled, the voltage regulator output appears
on the V
characteristics. If the regulator is used to provide V
from Figure 11, but connect REGIN to an on-board 5 V supply, and disconnect it from the VBUS pin.

Connector
Note 1 : VIO can be connected directly to VDD or to a supply as low as 1.8 V to set the I/O interface
Note 2 : Avalanche transient voltage suppression diodes compatible with Full-speed USB should be
Note 3 : An external pull-up is not required, but can be added for noise immunity.
Note 4 : If programming the configuration ROM via USB, add a 4.7 F capacitor between VPP

and ground. During a programming operation, do not connect the VPP pin to other
circuitry, and ensure that VDD is at least 3.3 V.
