TPS7A4518DCQR from Texas Instruments, in a SOT-223-6. 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 | SHDN | input | Shutdown input accepting 5V or 3V logic levels with typical 3 μA input current; pull low to disable output or connect to VIN if unused. |
| 2 | IN | power_in | Power supply input requiring 1-10 μF ceramic bypass capacitor if more than six inches from main filter; protected against reverse voltage on both IN and OUT pins. |
| 3 | GND | power_in | Ground reference. |
| 4 | OUT | power_out | Regulated 1.8V output power supply requiring minimum 10 μF ceramic capacitor to prevent oscillations. |
| 5 | SENSE | input | Feedback input to error amplifier with 600 μA bias current at rated output voltage; connect to output for optimal regulation or to load to eliminate PCB trace voltage drops. |
| 6 | GND | power_in | Ground reference for DCQ package. |
