TL1963A-25DCQR 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 | Driving SHDN high (above 2 V, VIH max 20 V) enables the device and driving it low (below 0.25 V) disables it; if unused it must be tied to VIN, and the pin has a weak internal pull-down so it disables the device when open. |
| 2 | IN | power_in | Input supply pin; for the old-chip TL1963A-xx the input must be at least VOUT + VDO and no more than 20 V, and reverse-current protection applies when OUT is held above IN. |
| 3 | GND | power_in | Ground pin, which must be connected to the exposed thermal pad on the PCB. |
| 4 | OUT | power_out | Regulator output that delivers up to 1.5 A and requires a capacitor of at least 10 µF with ESR of 3 Ω or less from OUT to ground for stability, placed as close to the pin as possible. |
| 5 | SENSE/ADJ | input | For the fixed-voltage TL1963A-25 this SENSE pin is the error-amplifier input and must be connected to OUT for proper operation, with the SENSE bias current specified as ISENSE in the electrical characteristics. |
| 6 | GND | power_in | Second ground pin, which is tied to the same ground net as pin 3 and the exposed thermal pad. |
