Changjing · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L
CJ6376A50MR 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; the recommended supply voltage range is 2.5V to 36V, and the absolute maximum input voltage is 40V. |
| 2 | VSS | power_in | Ground reference pin for the regulator. |
| 3 | CE | input | Chip enable input; a logic high is 1.5V minimum up to VIN, a logic low is 0.3V maximum, and the CE pin voltage is rated -0.3V to 33V. |
| 4 | NC | unconnected | No connection. |
| 5 | VOUT | power_out | Regulated output, adjustable in 1.2V to 12V steps for this series, delivering up to 300 mA; absolute maximum output voltage is 13V. |
