TPS7A4501KTTR 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 input; pull low to disable output, leave high or open-collector with pullup resistor to enable; typically 3 μA pullup current required. |
| 2 | IN | power_in | Power supply input; requires 1 μF to 10 μF ceramic bypass capacitor if more than six inches from main input filter capacitor; absolute maximum ±20 V. |
| 3 | GND | power_in | Ground reference; exposed thermal pad must be soldered to PCB for rated thermal performance. |
| 4 | OUT | power_out | Regulated power supply output; minimum 10 μF ceramic output capacitor required to prevent oscillations. |
| 5 | ADJ | input | Error amplifier adjustment input (adjustable version only); internally clamped to ±7 V with 3 μA bias current; 1.21 V to 20 V output voltage range. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
