The TPS7H3301-SP from Texas Instruments is a radiation-hardened, 3A sink and source DDR termination regulator designed for space applications. It features a built-in VTTREF buffer and supports DDR, DDR2, DDR3, DDR3L, and DDR4 termination. The regulator operates from a 2.5-V or 3.3-V rail, with an option for a separate low-voltage input down to 0.9 V for improved efficiency.
Key electrical specifications include an output voltage range of 0.5 V to 1.75 V for VTT, and a typical quiescent current of 18 mA. The device offers ±10 mA sink and source current for the VTTREF buffer. It is qualified to 100 krad(Si) total ionizing dose and is immune to SEL, SEGR, and SEB up to LET = 70 MeV-cm²/mg.
The TPS7H3301-SP is available in a 16-pin CFP package. It includes an enable input and a power-good output for power supply sequencing. The operating temperature range is -55°C to 125°C, making it suitable for demanding environments.
This regulator is ideal for command and data handling (C&DH), optical imaging payloads, and radar imaging payloads in space-constrained systems requiring stable DDR termination.
The device supports 2.5V and 3.3V main rails, a separate VLDOIN input down to 0.9V, and a Vin bias range of 2.375V to 3.5V.
The VTT output voltage range is 0.5V to 1.75V.
The operating temperature range is -55°C to 125°C.
The device is available in a CFP (HKR) surface-mount package.
The VTT output provides 3A sink/source current, and the VTTREF output provides ±10mA sink/source current.
Total ionizing dose of 100 krad(Si). Immune to single-event latch-up at LET = 70 MeV-cm²/mg.
VTTREF accuracy is 49% to 51% of VDDQSNS.
