The UA78M fixed-voltage integrated-circuit voltage regulator is designed for a wide range of applications. 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 500mA of output current. Additionally, the UA78M does not need external components 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.
