Summary

The Texas Instruments TPS7H3301-SP is a sink and source double data rate (DDR) termination regulator designed for space applications with built-in VTTREF buffer.

The component is specifically designed to be a compact, low-noise solution for applications with space and weight limitations. The space DDR termination applications include solid state recorders, single board computers, and payload processing. 

During read/write conditions, the fast transient response feature of the component enables stable supply. Any voltage offset between VTT/Vo and VTTREF are minimized by the fast tracking feature of the VTTREF during transients. DDR VTT termination applications is supported by the TPS7H3301-SP using DDR, DDR2, DDR3, DDR4.

The component can be integrated with an enable input and an open-drain power-good output (PGOOD) to enable simple power sequencing. To monitor when all supplies have come into regulation. PGOOD output can be tied to multiple open-drain outputs. During suspend to RAM (S3) power down mode, VTT/Vo can be discharged using enable signal.

The product is radiation hardened, space-graded and is tested for on-orbit Single Event Effects (SEE) event rates in LEO and GEO using Cosmic Ray Effects on Micro-Electronics 96 (CREME96).
