About this product
A fixed negative linear voltage regulator in a TO-220 package, providing a regulated -5 V output for negative supply rails in analog and mixed-signal circuits. It is commonly used to create a negative rail for op-amps and other circuits from a higher negative unregulated input. It needs an input voltage several volts more negative than its output, and a heatsink at higher load currents.

How much input voltage does the L7905CV need?
The input must be more negative than -5 V by the dropout margin, typically around 2 V, plus enough headroom for ripple. Feeding it a higher input voltage increases heat in the package, so check the datasheet for the maximum input rating.
Does it need a heatsink and capacitors?
At currents close to 1 A, or when the input-to-output voltage difference is large, the regulator gets hot and needs a heatsink. Typical designs add input and output capacitors near the regulator for stability, as recommended in the datasheet.
