# LM79L06

**HTC Korea TAEJIN Tech** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-92

LM79L06 from HTC Korea TAEJIN Tech, 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 | Ground reference pin of the negative regulator. |
| 2 | VIN | power_in | Negative input voltage pin; for the LM79L06 the recommended input range is -8V to -20V and the absolute maximum input voltage for the LM79L05 to LM79L09 family is -30V. |
| 3 | VOUT | power_out | Negative regulated output pin, nominally -6.0V for the LM79L06 (-5.7V to -6.3V over temperature at 1mA to 70mA load), with output current up to 100mA. |
