5 V fixed LDO in a TO-220 — what it delivers
The LM2931AV50 is a 5 V fixed-output low-dropout regulator from ON Semiconductor, delivering up to 100 mA in a TO-220-3 through-hole package. It is a single positive-output LDO with a maximum input voltage of 26 V and a dropout voltage of 0.6 V at full load.
ON Semiconductor has marked the LM2931AV50 as obsolete. For a production BOM, this means any future replenishment depends on existing inventory in the independent distribution channel.
Key parametrics for the BOM fit
Protection features include current limit and thermal shutdown, so the part can handle brief overloads or a shorted output without immediate failure. The TO-220 package with its exposed metal tab can dissipate several watts with a heatsink — useful if the load is continuous near the 100 mA limit and the input-output differential is high.
