Changjing · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2L
CJ78M06 from Changjing, in a TO-252-2L. 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 | IN | power_in | Unregulated input voltage to the regulator, with an absolute maximum input voltage of 35 V; a 0.33 μF input bypass capacitor (Ci) is recommended close to the regulator. |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | OUT | power_out | Regulated 6 V output, rated for a maximum output current (IOM) of 0.5 A; a 0.1 μF output bypass capacitor (Co) is recommended close to the regulator. |
