Additional Details:

The LM79L12TA is typically available in a TO-92 package. It is recommended to use bypass capacitors on the input and output to improve stability and transient response. The input voltage should be at least a few volts more negative than the output voltage (-12V) to ensure proper regulation. Detailed electrical characteristics, application circuits, and thermal considerations can be found in the product datasheet. This negative voltage regulator is a simple and reliable solution for applications requiring a stable -12V supply voltage with a moderate current demand.
