Okay, here's a summary of the electrical characteristics data provided, extracted and organized for easy comparison. I'll present it in a table format, covering the key parameters for each of the L79Lxx series regulators detailed in the document.

Key Parameters Summary (from L79LxxAB/AC Datasheet)

| Regulator Model | Output Voltage (V) | Line Regulation (mV) | Load Regulation (mV) | Quiescent Current (mA) | Output Noise (µV) | SVR (dB) | Dropout Voltage (V) |
|---|---|---|---|---|---|---|---|
| L79L05AB/AC | -5 | 150 | 60 | 6 | 40 | 41-49 | 1.7 |
| L79L06AB/AC | -6 | 150 | 60 | 6 | 50 | 39-46 | 1.7 |
| L79L08AB/AC | -8 | 175 | 80 | 6 | 60 | 37-45 | 1.7 |
| L79L09AB/AC | -9 | 225 | 80 | 6 | 70 | 37-44 | 1.7 |
| L79L12AB/AC | -12 | N/A | N/A | 6 | 70 | 37-44 | 1.7 |

Important Notes & Observations:

️· Dropout Voltage: All models consistently have a dropout voltage of 1.7V.
️· Quiescent Current: All models have the same quiescent current of 6mA.
️· Line Regulation: Line regulation varies, generally increasing as the output voltage increases.
️· Load Regulation: Load regulation is consistent at 80mV for most models, but varies slightly between those models.
️· Noise and SVR: Noise levels and Supply Voltage Rejection (SVR) show some variation, but generally follow a trend.
️· AB/AC: The AB and AC versions appear to have the same electrical characteristics.
