TPS7A4533DCQT 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 control; pull low to enter shutdown state; if unused, connect to VIN; typical shutdown current 3 μA; accepts 5V, 3V, or open-collector logic |
| 2 | IN | power_in | Power supply input; requires 1-10 μF bypass capacitor if located more than 6 inches from main filter; withstands ±20 V reverse voltage with <1 mA input current |
| 3 | GND | power_in | Ground reference |
| 4 | OUT | power_out | Regulated 3.3 V output; requires minimum 10 μF ceramic capacitor with ESR ≤ 3 Ω; maximum output current 1.5 A at 300 mV dropout; can supply up to 1 mA quiescent current |
| 5 | SENSE | input | Error amplifier feedback input for fixed-voltage mode; connect to OUT for local sensing or to load for remote Kelvin sensing to compensate parasitic PCB trace resistance; 600 μA bias current at rated output |
| 6 | GND | power_in | Ground connection; serves as exposed thermal pad in DCQ package and must be soldered to PCB for rated thermal performance |
