Overview

The LM7818CT is a voltage Regulators, Linear, Low Drop Out (LDO) Regulator made by onsemi in a TO-220 package with 3 pins. -40℃~+125℃@(Tj) 1 110uV 18V 1A 2V@(1A) 33V 5.2mA 69dB@(120Hz) Fixed Over Current Protection、Short Circuit Protection、Thermal shutdown Positive TO-220 Voltage Regulators - Linear, Low Drop Out (LDO) Regulators ROHS.

PCBKit's library has its KiCad symbol (Pinmap_Generic:Regulator_Linear_1IN_2GND_3OUT, from PCBKit's generic symbols) and its footprint (EasyEDA_Cloud:TO-220-3_L9.9-W4.5-P2.54-L, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C3751641). 4 open-source boards in 1 repository on GitHub use it.

Is there a KiCad symbol and footprint for the LM7818CT?

Yes. The symbol is Pinmap_Generic:Regulator_Linear_1IN_2GND_3OUT and the footprint EasyEDA_Cloud:TO-220-3_L9.9-W4.5-P2.54-L, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM7818CT?

TO-220, with 3 pins. Its footprint is drawn on this page.

Where is the LM7818CT datasheet?

onsemi publishes it: the Datasheet link on this page opens it.

Where can I order the LM7818CT?

JLCPCB lists it as part C3751641, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LM7818CT?

Parts like it in the library: the L7818CV(MS) by MSKSEMI, the MC7918CT by onsemi, the L7818CV-DG by STMicroelectronics and the KIA7818API-U/PF by KEC Semicon. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the LM7818CT?
