The LM7908 is a negative voltage regulator IC that provides a stable -8V output, making it suitable for circuits requiring a regulated negative voltage. It is part of the LM79XX series and can supply an output current in excess of 1A, with the ability to handle up to 1.5A with the appropriate heat dissipation.
The LM7908 features internal thermal overload protection, short circuit protection, and safe-area compensation, making it a reliable and efficient choice for electronic circuits requiring stable negative voltage sources. This IC is ideal for applications that need a high ripple rejection and a low tolerance of 4% on the preset output voltage.
The LM7908 comes in a TO-220 package and only requires a single external compensation capacitor at the output for optimal performance.
