Additional Details:

The TS79L18CYRM is a three-terminal regulator that requires only input and output capacitors for stable operation. The internal thermal overload protection automatically shuts down the regulator if the junction temperature exceeds a safe limit. The short-circuit current limiting prevents the regulator from being damaged in the event of a short circuit at the output. The output transistor safe-area compensation ensures that the regulator operates within its safe operating area, even under varying load conditions. Proper heat sinking might be required depending on the input voltage and output current. Consult the device datasheet for specific application details and recommended component values. This regulator delivers a dependable and economical approach to generating a consistent -18V supply.
