The Microchip CL2N3-G is a linear constant-current LED driver that delivers a regulated 20mA per channel from a supply up to 90V, in a through-hole TO-92-3 package. The constant-current topology means the LED current stays fixed regardless of forward voltage variation along a string — no external current-setting resistor needed, which simplifies the BOM for single-channel indicator or channel-letter applications.
Housed in the TO-226-3 / TO-92-3 (TO-226AA) package, it mates with standard 0.100-inch pitch through-hole layouts — the same footprint used by general-purpose transistors and voltage references, so no board respin if swapping from a different TO-92 part. The three-lead TO-92 body is self-supporting on the PCB; no extra hold-down required for vibration environments common in signage and architectural lighting.
RoHS3 compliant, with the full Microchip traceability and date-code pedigree expected for a catalog part. Sourced through independent distribution; availability and pricing confirmed at RFQ against your target quantity.
