STMicroelectronics +12V Fixed Voltage Regulator TO-220

This STMicroelectronics +12V Fixed Voltage Regulator is a robust 3-terminal positive device designed to provide local on-card regulation, effectively eliminating the distribution problems associated with single-point regulation. It is an ideal solution for power management applications requiring a stable and reliable voltage supply.

Featuring internal current limiting, thermal shut-down, and safe area protection, this integrated circuit offers exceptional reliability and robust protection under demanding conditions. If adequate heat sinking is provided, the device can deliver an output current of over 1A, with a maximum output capacity of 1.5A. Although primarily designed as a fixed voltage regulator, it can also be utilised with external components to obtain adjustable voltages and currents, providing versatile application options.
