STMicroelectronics +5.0V Voltage Regulator 78M05 TO-220-3
STMicroelectronics 78M05 fixed +5V voltage regulator in 3-pin TO-220 package. Delivers up to 0.5A with thermal & short circuit protection.
The STMicroelectronics 78M05 Voltage Regulator is a fixed output, three-terminal precision positive voltage regulator housed in a 3-pin TO-220 package. It provides local on-card regulation, effectively eliminating distribution problems associated with single point regulation for a more reliable power management solution.
Designed with robust safety features, this regulator includes thermal overload protection that shuts down the circuit during excessive power conditions, alongside internal short circuit protection that limits the maximum current the circuit will pass. It also features output transistor safe area compensation, which reduces the output short circuit current as the voltage across the pass transistor increases. If adequate heat sinking is provided, this positive voltage regulator can deliver an output current of over 0.5A.
