LM2776DBVR from Texas Instruments, in a SOT-23-6. 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 | VOUT | power_out | Negative voltage output. Delivers the inverted supply (approximately -VIN) up to 200 mA continuous. Bypass to GND with a 2.2 μF ceramic capacitor. |
| 2 | GND | power_in | Power supply ground input. Serves as the return reference for VIN and as the positive rail of the inverted output (VOUT is negative relative to GND). |
| 3 | VIN | power_in | Power supply positive voltage input, 2.7 V to 5.5 V (6 V absolute max). Bypass to GND with a 2.2 μF ceramic capacitor. |
| 4 | EN | input | Enable control pin. Tie high (EN = 1, VIH ≥ 1.2 V) for normal operation, or tie to GND (EN = 0, VIL ≤ 0.4 V) for shutdown. Absolute range: (GND − 0.3 V) to (VIN + 0.3 V). |
| 5 | C1+ | passive | Positive terminal connection for the external 1 μF flying (charge-pump) capacitor. Connect between C1+ and C1-. |
| 6 | C1- | passive | Negative terminal connection for the external 1 μF flying (charge-pump) capacitor. Connect between C1+ and C1-. |
