MC79L15ABPG

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

MC79L15ABPG from onsemi, in a TO-92. 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 GND power_in Common ground reference for the regulator; the datasheet requires a common ground between the input and output voltages and recommends minimizing ground loops and lead resistance drops because the regulator has no external sense lead.
2 Input power_in Negative unregulated input, rated at a maximum of −35 Vdc for the −12, −15 and −18 V devices, and the input must remain typically 2.0 V above the output voltage even at the low point of the ripple.
3 Output power_out Regulated −15 V nominal output (−14.25 V to −15.75 V at 1.0 mA ≤ IO ≤ 70 mA over the specified input range), with internal short-circuit current limiting and thermal overload protection, and a load range of 1.0 mA to 100 mA.
