TPS7A4533DCQR from Texas Instruments, in a SOT-223-6. 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 | SHDN | input | Shutdown input; output disabled when pulled low; if unused, connect to VIN; supports 5-V, 3-V, or open-collector logic with typical 3 μA current draw. |
| 2 | IN | power_in | Power supply input; requires 1-10 μF ceramic bypass capacitor if >6 inches from main filter capacitor; withstands ±20 V reverse voltage with inherent diode-like protection. |
| 3 | GND | power_in | Ground reference providing return path for all device currents. |
| 4 | OUT | power_out | Regulated 3.3 V output; requires minimum 10 μF ceramic capacitor with ESR ≤3 Ω for stability; supplies up to 1.5 A to load. |
| 5 | SENSE | input | Feedback input to error amplifier; connect to OUT for regulation or to load for Kelvin sensing to compensate voltage drops; 600 μA bias current at rated output voltage. |
| 6 | GND | power_in | Ground connection; must be soldered to PCB for proper thermal performance (DCQ package). |
