TL1963A-25DCYT from Texas Instruments, in a SOT-223-4. 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 | IN | power_in | Input supply pin; for the new-chip version VIN must be 2.4 V to 20 V, and for the old chip VIN must be at least VOUT + VDO with an absolute maximum of 20 V. |
| 2 | GND | power_in | Ground pin; the exposed thermal pad on the DCY package is also ground and must be soldered to the PCB to achieve the rated thermal performance. |
| 3 | OUT | power_out | Regulator output that requires a capacitor of at least 10 µF with ESR of 3 Ω or less from OUT to GND for stability, placed as close to the pin as possible. |
| 4 | GND | power_in | Ground pin; the exposed thermal pad on the DCY package is also ground and must be soldered to the PCB to achieve the rated thermal performance. |
