Changjing · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L
CJ6109B33M 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, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Power input pin; the datasheet specifies an input voltage range of 1.6 V to 6.0 V. |
| 2 | VSS | power_in | Ground pin; all voltages are referenced to the network ground terminal. |
| 3 | CE | input | Chip enable pin; a level of 1.5 V to VIN enables the regulator and 0.3 V maximum shuts it down, with shutdown current of 1.0 µA max when CE = VSS. |
| 4 | NC | unconnected | No connection. |
| 5 | VOUT | power_out | Regulated output pin; the datasheet lists 1.0 A typical guaranteed output current and recommends a 4.7 µF or larger output capacitor. |
