TPS51100 - Texas Instruments

TPS51100 Source DDR Termination Regulator

The TPS51100 is a 3-A, sink/source tracking termination regulator. The device is specifically designed for low-cost and low-external component count systems where space is a premium. The TPS51100 maintains fast transient response, only requiring 20 μF (2 × 10 μF) of ceramic output capacitance. The TPS51100 supports remote sensing functions and all features r.
