The regulator is specifically design 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 and is compliant to DDR, DDR2, DDR3, DDR4, and associated low-power JEDEC specifications. 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 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 during suspend to RAM (S3) power down mode.

VIN is 2.95 to 3.5 V for DDR1 and VLDOIN > VTT for all DDRs. For DDR2 3-A load condition, VIN is 2.45 to 3.5 V. VIN headroom: VIN_MIN = VTT + 1.5 V. (3) These units are intended for engineering evaluation only. They are processed to a noncompliant flow (that is, no burn-in, and so forth) and are tested to a temperature rating of 25°C only. These units are not suitable for qualification, production, radiation testing or flight use. Parts are not warranted for performance over the full MIL specified temperature range of –55°C to 125°C or operating life.
