The TPS7H3302 is a 3-A sink and source tracking termination regulator incorporating a high performance, low-dropout (LDO) linear regulator specifically designed for low input voltage, and low external component count systems where board area is a key application parameter. The LDO regulator employs a fast feedback loop so that ceramic capacitors can be used to support the fast load transient response. To achieve tight regulation with minimum effect of trace resistance, a remote sensing pin (VTTSNS) should be connected to the positive pin of the output capacitor(s) as a separate trace from the high-current path of VTT.

The TPS7H3302 has a dedicated pin (VLDOIN) for connection to the VTT power supply, in order to minimize the LDO power dissipation. The minimum VLDOIN voltage is highlighted in Electrical Characteristics : TPS7H3302 (VLDOIN to VTT headroom) for various load conditions.
