APPLICATION INFORMATION (continued)

Figure 11. Peripheral-Side (Low-Speed) Internal Regulator Mode

Only for TUSB1105

While operating at full speed, the 1.5-k

Ω resistor must be connected between the D+ line and the V

PU(3.3) or an

external 3.3-V supply. If there is no 3.3-V supply on the board, the internal regulator can be used to provide the

3.3-V supply for the USB signaling. The VCC(5.0) is connected to a 5-V supply that generates the 3.3-V rail at the

Vreg(3.3) pin. In this mode, it is important that both VCC(5.0) and Vreg(3.3) pins have individual bypass capacitors in

the range of 0.1

µF.
