Overview

The LR7805 is a voltage Regulators Linear, Low Drop Out (LDO) Regulator made by Leshan Radio (LRC) in a TO-220 package with 3 pins. -40℃~+125℃@(Ta) 1 1A 2V 35V 42uV 5V 73dB@(120Hz) 8mA Fixed Over Temperature Protection、Short Circuit Protection 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:SW-TH_DS-080-CPA, from EasyEDA), ready for a KiCad board. 361 are in stock at JLCPCB (part C2846986).

Questions

Is there a KiCad symbol and footprint for the LR7805?

Yes. The symbol is Pinmap_Generic:Regulator_Linear_1IN_2GND_3OUT and the footprint EasyEDA_Cloud:SW-TH_DS-080-CPA, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LR7805?

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

Where is the LR7805 datasheet?

Leshan Radio (LRC) publishes it: the Datasheet link on this page opens it.

Where can I order the LR7805?

JLCPCB lists it as part C2846986, with 361 in stock; the sellers' links on this page open their listings.

What can replace the LR7805?

Parts like it in the library: the LR7805-J by LR, the UA7805CKCT by Texas Instruments, the AMS1117-5.0 by Advanced Monolithic Systems and the L7805CDT-TR by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
