Product Introduction

Overview

The MC7808BTG is a member of the MC7800 Series of positive linear voltage regulators produced by onsemi. These regulators are monolithic integrated circuits designed as fixed-voltage regulators for a wide variety of applications, including local, on-card regulation. The MC7808BTG specifically provides a fixed output voltage of 8 volts.

These devices are known for their robust features such as internal current limiting, thermal shutdown, and safe-area compensation, making them reliable for high-current applications. With adequate heatsinking, they can deliver output currents in excess of 1.0 A.
