Texas Instruments has introduced a double-data-rate (DDR) memory linear regulator for space applications, claimed to be the industry’s first. The TPS7H3301-SP is the only DDR regulator immune to single-event effects up to 65 megaelectron volts per centimetre squared (MeV-cm2), powering space-satellite payloads including single-board computers, solid-state recorders and other memory applications.
Integrating two monolithic power FETs for source and sink termination and an internal voltage reference, the device is up to 50 percent smaller than a switch-mode regulator DDR solution.
Designers can reduce development time and quickly complete worst-case circuit analysis by downloading a full-capability linear regulator SPICE model.
It is available in a 16-pin dual-ceramic flat package that is Qualified Manufacturer List (QML) Class V and 100krad (silicon) radiation hardness assurance (RHA) qualified (5962R1422801VXC).
