The UA78M fixed-voltage integrated-circuit voltage regulators is designed for a wide range of applications. Use the UA78M for on-card regulation to eliminate noise and distribution problems associated with single-point regulation. The UA78M is also used with power-pass elements to make high-current voltage regulators. The UA78M delivers up to 500mA of output current. Additionally, the UA78M does not need an external capacitor 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. See the Device Nomenclature table for more details.
