MC78M18CDTG Description

Short technical summary and product information.

The MC78M18CDTG from ON Semiconductor is a three-terminal positive voltage regulator designed for local, on-card voltage regulation. It offers a fixed output voltage of 18V and can supply a maximum output current of 500mA. This device is suitable for applications requiring a stable voltage supply without external components.

 

Key features include internal current limiting, thermal overload protection, and output transistor safe-area compensation, making it robust under various operating conditions. The regulator operates within a temperature range of 0°C to 125°C. It is packaged in a TO-252-3, DPak (2 Leads + Tab), SC-63, designed for surface mounting.

 

This regulator is part of the MC78M00 series, which is similar to the MC7800 series but specified for half the output current. The MC78M18CDTG is designed for applications where a reliable and regulated positive voltage is essential, such as in power supplies and local voltage regulation circuits.
