8.3.1 Sink and Source Regulator (VO Pin)

The TPS51200A-Q1 device is a sink and source (sink/source) tracking termination regulator specifically designed for low input voltage, low-cost, and low external-component count systems where space is a key application parameter. The TPS51200A-Q1 device integrates a high-performance, low-dropout (LDO) linear regulator that is capable of both sourcing and sinking current. The LDO regulator employs a fast feedback loop so that small 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, VOSNS, must be connected to the positive pin of the output capacitors as a separate trace from the high current path from the VO pin.
