LT3029-Slide4

The LT3029 may be thought of as a monolithic, higher current version of the LT3028, or two times an LT1763 in one package. The LT3029, when compared to the LT3028, features lower reference voltage; higher output current on the second LDO; higher output voltage accuracy over line, load, and temperature (±2% vs. ±2.5%); and smaller packages with better thermal characteristics. The LT3029 does not include reverse output protection, and has a higher quiescent current per regulator (55µA vs. 30µA). Compared to using two LT1763 devices as an alternative, it is clear the LT3029 will offer a much more compact solution, with better performance on some parameters including wider VIN range, higher accuracy and smaller packages, with the only minor “penalties” being higher quiescent current and no reverse output protection.
