Changjing · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3L
CJ6101A30M from Changjing, in a SOT-23-3L. 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 | VSS | power_in | Ground pin and network ground reference for all voltages in the datasheet, with the regulator's voltages specified with respect to this terminal. |
| 2 | VOUT | power_out | Regulated output pin with output voltage range 1.2 V to 5.0 V and output current up to 300 mA, requiring a 1 µF capacitor from OUT to GND placed close to the pins for loop stability. |
| 3 | VIN | power_in | Power input pin with recommended supply range 1.8 V to 8 V (absolute maximum -0.3 V to 9 V), bypassed with a 1 µF input capacitor. |
