9.4.1 VDD33 Regulator

The VDD33 internal LDO regulator powers the USB PHY, charger detection, and OTG functions of the USB subchip inside TUSB1210. Section 6.12 describes the regulator characteristics.

VDD33 regulator takes its power from VBAT.

Since the USB2.0 standard requires data lines to be biased with pullups biased from a supply greater than 3 V, and since VDD33 regulator has an inherent voltage drop from its input, VBAT, to its regulated output, TUSB1210 will not meet USB 2.0 Standard if operated from a battery whose voltage is lower than 3.3 V.
