TL1963AQKTTRQ1 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 | SHDN | input | Shutdown control pin, active-low to disable regulator, accepts 5-V logic or open-collector logic with typical 3 µA pin current, must be tied to VIN if unused. |
| 2 | IN | power_in | Power input pin with voltage range from VOUT + VDO to 20 V, includes integrated reverse-battery protection. |
| 3 | GND | power_in | Ground reference connection. |
| 4 | OUT | power_out | Regulated power output with maximum 1.5 A output current capability. |
| 5 | ADJ/SENSE | input | Error amplifier feedback input clamped to ±7 V internally; in adjustable mode provides 1.21 V reference for 1.21-20 V output with 3 µA bias current; in fixed-voltage mode has 600 µA bias current. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
