SLVK174 September 2024 TPS7H1121-SP
The TPS7H1121-SP is a radiation-hardened, low-dropout linear regulator (LDO) which operates over a wide input voltage range and is optimized for powering devices in a space environment. The device is capable of sourcing up to 2A over a 2.25V to 14V input. SEE testing on this device was completed with both pre-production and production units. Pre-production units refer to P-type symbolized units that have not completed Texas Instrument's Space Enhanced Product (SEP) qualification flow.
The device offers excellent stability and features a programmable current limit with a wide adjustment range. To support the complex power requirements of FPGAs, DSPs, and micro-controllers, the TPS7H1121-SP provides enable on and off functionality, programmable soft start, and a power good open-drain output.
The device is offered in a 22-pin ceramic package. General device information and test conditions are listed in Table 1-1. For more detailed technical specifications, user-guides, and application notes please go to TPS7H1121-SP product page.
