CJ6206B12M from Changjing, in a SOT-23-5L. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). Symbol and footprint from KiCad-official CAD; the 3D model is generated from the datasheet's package dimensions.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Power input pin; the operating input voltage is 2.0V to 7.0V, and the absolute maximum input voltage is VSS-0.3 to VSS+8 V. |
| 2 | VSS | power_in | Ground pin, the reference for the input, output and CE signals. |
| 3 | CE | input | TTL-logic chip enable input; a high level of 1.5V up to VIN enables the output, and a low level of 0.3V or less puts the regulator in shutdown with about 0.1 μA standby current. |
| 4 | NC | unconnected | No connection; this pin is not connected internally. |
| 5 | VOUT | power_out | Regulated output pin; the specified output current is 300 mA, with a short-circuit current of 50 mA at VOUT = VSS. |

Package_TO_SOT_SMD:SOT-23-5 - 3D model: SOT-23-5L, generated on the KiCad land (body 1.6 x 2.92 mm, terminals on the pads, 1.15 mm tall, datasheet A, midpoint of min and max). KiCad's stock model for this land is taller than the datasheet allows, so the model is generated from the datasheet drawing; the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
