Changjing · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3L
CJ8850 from Changjing, in a SOT-89-3L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Device ground / VSS return. All voltages in the datasheet are referenced to this node. Connect directly to the system ground plane and to the ground side of both CIN and COUT with the shortest possible trace. |
| 2 | IN | power_in | Regulator input supply (VIN). Recommended operating range 2.5V to 60V; absolute maximum -0.3V to 65V. Bypass with a ≥1.0μF ceramic capacitor placed as close as possible between IN and GND to avoid start-up voltage transients (a 3Ω series resistor with an X5R MLCC is suggested when the input is hot-plugged). |
| 3 | OUT | power_out | Regulated output (VOUT). Fixed 5.0V nominal for the CJ8850 option, ±2% typical accuracy, up to 150mA continuous (400mA absolute-max IOUT, internal current limit 150-250mA). Bypass with a ≥1.0μF ceramic capacitor to GND (10μF recommended) with appropriate ESR for phase compensation. |
