STMicroelectronics +12V Fixed Voltage Regulator, TO-220
STMicroelectronics +12V fixed voltage regulator in a TO-220 package. Features thermal overload & short-circuit protection. 500mA output current.
The STMicroelectronics +12V Fixed Voltage Regulator is a robust three-terminal positive voltage regulator designed for a wide range of power management applications. This device provides reliable local on-card regulation, effectively eliminating the distribution issues associated with single-point regulation.
Built to withstand demanding conditions, the regulator employs internal current limiting, thermal shutdown, and safe operating area protection, making it highly resistant to damage. When used with an adequate heat sink, it can deliver an output current of over 0.5A. Although primarily designed as a fixed voltage regulator, it can also be utilised with external components to achieve adjustable voltage and current outputs.
