UC285TDKTTT-3 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 | VB | power_in | Supplies power to all circuits of the regulator except the output power transistor, and needs 2 V of headroom above VOUT (absolute maximum VB is 13 V). |
| 2 | VIN | power_in | Supplies current only to the collector of the output power transistor, with maximum dropout of 490 mV at 5 A for TJ = 0°C to 100°C (absolute maximum VIN is 7.5 V). |
| 3 | GND | power_in | Should be referenced to the load ground for accurate results; the TO-263 tab is also ground. |
| 4 | ADJ | input | In the adjustable version, two external 0.1% resistors program the output voltage, with R3 |
| 5 | VOUT | power_out | Connect to the load through a low-impedance path, since the Kelvin sense point is at this pin and trace voltage drops add to the dropout voltage. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
