TPS7B4250QDBVRQ1 from Texas Instruments, in a SOT-23-5. 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 | ADJ/EN | input | Reference voltage input for output voltage adjustment and enable/disable control; level ≥1.5V enables IC, level ≤0.8V disables IC. |
| 2 | GND | power_in | Ground reference, internally connected to pin 5. |
| 3 | VIN | power_in | Unregulated input supply voltage accepting 4V to 40V; bypass capacitor recommended adjacent to IC for line rejection. |
| 4 | VOUT | output | Regulated output voltage; external capacitor of 1µF to 50µF with ESR of 0.001Ω to 20Ω required between VOUT and GND for stability. |
| 5 | GND | power_in | Ground reference, internally connected to pin 2. |
