onsemi · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOIC-8

MC79L05ABDR2G from onsemi, in a SOIC-8. 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 Vout power_out Regulated negative output, nominally −5.0 V, held between −4.75 V and −5.25 V over the stated input and load conditions, with a 0.1 µF output capacitor CO recommended to improve stability and transient response.
2 Vin power_in Unregulated negative input, with a maximum input voltage of −30 Vdc for the −5 V device and an input of typically at least 2.0 V above the output voltage needed even at the ripple low point.
3 Vin power_in Unregulated negative input (same net as pin 2 per the input pin group), limited to −30 Vdc maximum for the −5 V device and bypassed with a 0.33 µF capacitor CI when the regulator is far from the supply filter.
4 NC unconnected No connection; the datasheet pinout lists this pin as NC and gives no electrical function for it.
5 GND power_in Common ground that must be shared between the input and output voltages, with ground-loop and lead-resistance drops minimized because the regulator has no external sense lead.
6 Vin power_in Unregulated negative input (same net as pin 2 per the input pin group), limited to −30 Vdc maximum for the −5 V device.
7 Vin power_in Unregulated negative input (same net as pin 2 per the input pin group), limited to −30 Vdc maximum for the −5 V device.
8 NC unconnected No connection; the datasheet pinout lists this pin as NC and gives no electrical function for it.
