The UA78M-Q1 fixed-voltage, integrated-circuit voltage regulator is designed for a wide range of applications. The UA78M-Q1 also functions with power-pass transistors to make high-current voltage regulators. The UA78M-Q1 delivers up to 500mA of output current. Additionally, the UA78M-Q1 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-Q1 is characterized for the junction temperature range of –40°C to +125°C. See the Device Nomenclature table for more details.
