About this product
The L7918 is a fixed negative linear voltage regulator that delivers a stable -18V output at up to 1.5A, housed in a TO-220 package. It is used to create negative supply rails for op-amps, audio circuits and analog designs, and is often paired with a positive regulator such as the L7818 in dual-supply setups.

What input voltage do I need for the L7918?
The input must be more negative than -18V by the regulator's dropout margin, so use a negative input several volts below -18V. Check the datasheet for the exact dropout and maximum input voltage.
Does the L7918 need a heatsink?
It dissipates the voltage difference between input and output multiplied by the load current as heat. For a large input-output difference or a current close to 1.5A, mount it on a heatsink. Add the input and output capacitors recommended in the datasheet close to the regulator.
