Changjing · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3L
CJ78L06 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 | OUT | power_out | Regulated +6 V output (5.7-6.3 V over line/load/temperature). Sources up to 100 mA. A 0.1 uF ceramic bypass capacitor to GND, mounted close to the pin, is recommended for stability and transient response. |
| 2 | GND | power_in | Common ground reference for the input and output. Also the SOT-89 heat-slug tab pin providing the thermal path to the PCB copper. |
| 3 | IN | power_in | Unregulated input, absolute maximum 30 V. Must be at least ~1.7 V above VOUT (typical dropout at 25 C) for regulation. A 0.33 uF ceramic input capacitor to GND, mounted close to the pin, is recommended. |
