Changjing · Linear Voltage Regulators (LDO) · TO-92-3
CJ79L05-TA from Changjing, 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 | GND | power_in | Ground reference pin of the negative regulator, connected to the common ground of input and output capacitors (Ci 0.33µF, Co 0.1µF). |
| 2 | IN | power_in | Negative input voltage pin, absolute maximum -30 V, with specified operation from -7 V to -20 V. |
| 3 | OUT | power_out | Regulated -5 V output pin (typ -5.0 V, -4.75 V to -5.25 V) supplying up to 0.1 A maximum output current. |
