TPS7A4901DGNT from Texas Instruments, in a MSOP-8-EP. 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 | OUT | output | Regulator output; a capacitor ≥ 2.2 µF must be tied from this pin to ground to ensure stability. |
| 2 | FB | input | Input to the error amplifier; FB is used to set the output voltage of the device. |
| 3 | NC | unconnected | Not internally connected; this pin can either be left open or tied to GND. |
| 4 | GND | power_in | Ground pin, must be tied directly to the PowerPAD under the device. |
| 5 | EN | input | Enable input that turns the regulator on when VEN ≥ VEN(high) and off when VEN ≤ VEN(low); can be connected to IN if not used, VEN ≤ VIN. |
| 6 | NR/SS | passive | Noise-reduction/soft-start pin; an external capacitor here bypasses band-gap noise to reduce RMS output noise and sets the soft-start ramp time. |
| 7 | DNC | unconnected | Do not connect; do not route this pin to any electrical net, not even GND or IN. |
| 8 | IN | power_in | Input supply pin, input voltage range 3 V to 35 V (recommended operating conditions). |
| 9 | PowerPAD | power_in | Exposed thermal pad; must be either left open or tied to ground, and should be soldered to the PCB ground plane to enhance thermal performance. |
