ONSEMI 78M12 Voltage Regulator +12V SMD DPAK-3

The ONSEMI 78M12 is a positive linear voltage regulator, offering reliable performance identical to the popular MC7800 series but specified for half the output current. Designed primarily for local, on-card voltage regulation, this three-terminal device provides a fixed 12V output, making it highly effective for a variety of power management applications.

This regulator is remarkably rugged under most operating conditions due to its comprehensive internal protection features. It includes internal current limiting, thermal shutdown circuitry, and safe-area compensation for the internal pass transistor. These features ensure robust performance and safeguard the component against typical operational stresses.

Delivering a maximum output current of 500mA with adequate heatsinking, the regulator requires no external components to function, simplifying circuit design and board layout. It operates within an input voltage range of 19V to 35V and across an operating temperature range of 0°C to 125°C.
