LT6654AHS6-1.25#TRPBF from Analog Devices, in a TSOT-23-6. 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 | GND | power_in | Internal function pin that must be tied to ground near Pin 2. |
| 2 | GND | power_in | Primary device ground. |
| 3 | DNC | unconnected | Do not connect; keep leakage current from this pin to VIN or GND to a minimum. |
| 4 | VIN | power_in | Power supply input; bypass VIN with a 0.1µF capacitor to ground. |
| 5 | DNC | unconnected | Do not connect; keep leakage current from this pin to VIN or GND to a minimum. |
| 6 | VOUT | power_out | Output voltage; an output capacitor of 1µF minimum is required for stable operation. |
