MC78L15ABPG

onsemi · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-92-3

MC78L15ABPG from onsemi, in a TO-92-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUTPUT power_out Regulated 15 V output for the MC78L15ABPG, which is rated for TJ = −40° to +125°C.
2 GND power_in Common ground that must be shared between the input and output voltages, as the datasheet requires a common ground between them.
3 INPUT power_in Unregulated input that must remain typically 2.0 V above the output voltage even at the low point of the input ripple, with the 12 V to 18 V absolute maximum input rating of 35 Vdc.
