TPS75533KTTR from Texas Instruments, in a TO-263-5. 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 | EN | input | Enable input: a logic high shuts the device down and a logic low enables it, with shutdown reducing quiescent current to less than 1 µA at TJ = 25°C. |
| 2 | IN | power_in | Input voltage to the regulator, specified at 2.8 V minimum to 5.5 V maximum in the recommended operating conditions. |
| 3 | GND | power_in | Regulator ground; the datasheet states the tab is also GND. |
| 4 | OUTPUT | power_out | Regulated output voltage, with output current rated 0 to 5 A and an output capacitor of at least 47 µF with ESR of at least 200 mΩ required between OUT and GND for stability. |
| 5 | FB/PG | output | For the fixed-output TPS75533 this is an open-drain, active-low power-good output that goes low when VO reaches about 91% of the regulated voltage and goes high-impedance below about 89%, requiring a pullup resistor; maximum PG voltage is 6 V. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
