Overview

The 79L09 is a voltage Regulators, Linear, Low Drop Out (LDO) Regulator made by MDD in a SOT-89-3L package with 3 pins. 0℃~+150℃@(Tj) 1 1.7V 100mA 24V 4.1mA 45dB@(120Hz) 58uV 9V Fixed Negative SOT-89-3L Voltage Regulators - Linear, Low Drop Out (LDO) Regulators ROHS.

PCBKit's library has its KiCad symbol (Pinmap_Generic:Regulator_Linear_1GND_2IN_3OUT, from PCBKit's generic symbols) and its footprint (Package_TO_SOT_SMD:SOT-89-3, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C414032).

Questions

Is there a KiCad symbol and footprint for the 79L09?

Yes. The symbol is Pinmap_Generic:Regulator_Linear_1GND_2IN_3OUT and the footprint Package_TO_SOT_SMD:SOT-89-3, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the 79L09?

SOT-89-3L, with 3 pins. Its footprint is drawn on this page.

Where is the 79L09 datasheet?

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

Where can I order the 79L09?

JLCPCB lists it as part C414032, with 0 in stock; the sellers' links on this page open their listings.

What can replace the 79L09?

Parts like it in the library: the LR78L09A by Leshan Radio (LRC), the 78L09-150 by UMW, the 78L09 by HXY MOSFET and the 78L09T by Foshan Blue Rocket Elec. Check their datasheets: a part that fits the footprint may still differ in its ratings.
