Changjing · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L
CJ6388B50M 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 | VOUT | output | Regulated output pin; the series supplies output voltages from 1.2 V to 12.0 V with output current up to 150 mA. |
| 2 | VSS | power_in | Ground pin, which is the network ground reference for all voltages. |
| 3 | NC | unconnected | No connection. |
| 4 | CE | input | Chip enable pin; drive above 1.5 V (up to VIN) to enable the regulator and below 0.3 V to disable it, with standby current of 0.1 to 0.5 μA when CE = VSS. |
| 5 | VIN | power_in | Power input pin; the supply voltage range is 2.5 V to 60 V, and CIN of 1.0 μF or more should be connected between VIN and VSS as close to the pins as possible. |
