Use the UA78M for on-card regulation to attenuate post regulation noise and distribution problems associated with single-point regulation. The UA78M delivers up to 500m A of output current. Additionally, the UA78M does not need external ponents for stable operation across the load current range. The internal current-limiting and thermal-shutdown Features of this regulator help protect the device from overload. The UA78M is characterized for the junction temperature range of - 40°C to +125°C. Device performance for new and legacy chips is denoted throughout the document. See the Device Nomenclature table for more details. Package Information PART NUMBER PACKAGE(1) PACKAGE...
