TPS51100DGQRG4 Description

Short technical summary and product information.

The Texas Instruments TPS51100DGQRG4 is a 3A sink/source tracking termination regulator specifically designed for low-cost and low-external component count systems where space is a premium. It supports DDR, DDR2, DDR3, DDR3L, and LPDDR3 memory types, providing essential termination for DDR VTT bus requirements.

Key electrical specifications include an input voltage range of 1.2V to 3.6V and an output voltage range of 0.75V to 1.25V. The device features a typical quiescent current of 0.5mA and offers ±20mV accuracy for VTT and VTTREF through remote sensing. It requires only 20µF of ceramic output capacitance and supports Hi-Z in S3 and Soft-Off in S5 states.

Packaged in a 10-HVSSOP, the TPS51100DGQRG4 is suitable for surface mount applications. It operates within a temperature range of -40°C to 85°C, making it a robust choice for various electronic designs. The regulator includes built-in soft-start, UVLO, and OCL thermal shutdown, supporting JEDEC specifications for reliable DDR termination.
