DX2786-3.3V
Dersem · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOP-8
DX2786-3.3V from Dersem, in a SOP-8. 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 | VOUT1 | output | LDO output pin for the second output rail, set to 0.66 x VOUT per the datasheet; absolute max VOUT/VOUT1 pin voltage is -0.3 to 7 V (page 3). |
| 2 | GND | power_in | Chip ground reference pin. |
| 3 | VOUT | output | Main LDO output pin; the output voltage is internally set to 5 V, 3.3 V or 2.7 V depending on version (3.3 V: 3.2 to 3.4 V; absolute max VOUT pin voltage -0.3 to 7 V per page 3). |
| 4 | VDD | power_in | Chip supply pin: energy storage capacitor is connected from this pin to GND, and input energy is passed to the LDO output stage; VDD turn-on is 7.6 to 8 V, undervoltage 1.2 V, and absolute max supply voltage 9 V (page 3). |
| 5 | Drain | power_in | Internal power MOSFET drain connected to the AC input through the high-voltage start-up path; it supplies energy to the stage when the input voltage falls within the charging window; absolute max drain voltage 650 V (page 3). |
| 6 | Drain | power_in | Internal power MOSFET drain connected to the AC input through the high-voltage start-up path; it supplies energy to the stage when the input voltage falls within the charging window; absolute max drain voltage 650 V (page 3). |
| 7 | Drain | power_in | Internal power MOSFET drain connected to the AC input through the high-voltage start-up path; it supplies energy to the stage when the input voltage falls within the charging window; absolute max drain voltage 650 V (page 3). |
| 8 | Drain | power_in | Internal power MOSFET drain connected to the AC input through the high-voltage start-up path; it supplies energy to the stage when the input voltage falls within the charging window; absolute max drain voltage 650 V (page 3). |
