TL1963A-33DCYR from Texas Instruments, in a SOT-223. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | power_in | Regulator input supply. Accepts up to 20 V and up to VOUT+VDO minimum. A 1-uF to 10-uF bypass capacitor is required (especially when placed more than ~6 inches from the input filter cap). Reverse-battery tolerant. |
| 2 | GND | power_in | Ground reference for the regulator. The DCY package brings GND out on pin 2 as well as on the tab (pin 4). |
| 3 | OUT | power_out | Regulated 3.3-V output, 1.5-A capable. Requires a minimum 10-uF ceramic output capacitor for stability; larger caps recommended for large transient loads. |
| 4 | GND (Tab) | power_in | SOT-223 thermal tab, electrically connected to GND. Must be soldered to a PCB copper pour for rated thermal performance. |
