Overview

The 78L08 is a voltage Regulators Linear, Low Drop Out (LDO) Regulator made by MDD in a SOT-89-3 package with 3 pins. -40℃~+125℃@(Tj) 1 1.7V@(40mA) 100mA 23V 46dB@(120Hz) 4mA 54uVrms 8V Fixed Positive SOT-89-3 Voltage Regulators - Linear, Low Drop Out (LDO) Regulators ROHS.

PCBKit's library has its KiCad symbol (Pinmap_Generic:Regulator_Linear_1OUT_2GND_3IN, from PCBKit's generic symbols) and its footprint (Package_TO_SOT_SMD:SOT-89-3, from KiCad's library), ready for a KiCad board. 856 are in stock at JLCPCB (part C414024).

Questions

Is there a KiCad symbol and footprint for the 78L08?

Yes. The symbol is Pinmap_Generic:Regulator_Linear_1OUT_2GND_3IN 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 78L08?

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

Where is the 78L08 datasheet?

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

Where can I order the 78L08?

JLCPCB lists it as part C414024, with 856 in stock; the sellers' links on this page open their listings.

What can replace the 78L08?

Parts like it in the library: the 78L08-150 by UMW, the CJ78L08 by Jiangsu Changjing Electronics Technology (CJ), the 78L08 by UMW and the 78L08 by HXY MOSFET. Check their datasheets: a part that fits the footprint may still differ in its ratings.
