Current Source

Schematic symbol

Symbol for an ideal current source, which supplies a fixed current regardless of the voltage across it, with the arrow showing the direction. Used in schematics and simulations; in real circuits it's built with transistors, regulators like the LM317 or dedicated chips, for example to drive LEDs.
