The TPS7H3301-SP is a TID and SEE radiation-hardened double data rate (DDR) 3-A termination regulator with built-in VTTREF buffer. The regulator is specifically designed to provide a complete, compact, low-noise solution for space DDR termination applications such as single board computers, solid state recorders, and payload processing.

The TPS7H3301-SP supports DDR VTT termination applications using DDR, DDR2, DDR3, DDR4. The fast transient response of the TPS7H3301-SP VTT regulator allows for a very stable supply during read/write conditions. During transients, the fast tracking feature of the VTTREF supply minimizes any voltage offset between VTT/Vo and VTTREF. To enable simple power sequencing, both an enable input and a power-good output (PGOOD) have been integrated into the TPS7H3301-SP. The PGOOD output is open-drain so it can be tied to multiple open-drain outputs to monitor when all supplies have come into regulation. The enable signal can also be used to discharge VTT/Vo during suspend to RAM (S3) power down mode.
