TPS7A7200RGTT from Texas Instruments, in a VQFN-16-EP(3x3). 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 | SNS | input | Output voltage sense input pin for feedback regulation of the regulator output. |
| 2 | FB | input | Output voltage feedback pin connected to the error amplifier; connect 220-pF ceramic capacitor from this pin to OUT. |
| 3 | PG | output | Active-high open-drain power-good output indicating when regulated output voltage reaches 90% of target. |
| 4 | 50mV | input | Output voltage setting pin; connect to ground to increase output voltage by 50 mV or leave floating when not in use. |
| 5 | 100mV | input | Output voltage setting pin; connect to ground to increase output voltage by 100 mV or leave floating when not in use. |
| 6 | 200mV | input | Output voltage setting pin; connect to ground to increase output voltage by 200 mV or leave floating when not in use. |
| 7 | GND | power_in | Ground pin; connect to large-area ground plane. |
| 8 | 400mV | input | Output voltage setting pin; connect to ground to increase output voltage by 400 mV or leave floating when not in use. |
| 9 | 800mV | input | Output voltage setting pin; connect to ground to increase output voltage by 800 mV or leave floating when not in use. |
| 10 | 1.6V | input | Output voltage setting pin; connect to ground to increase output voltage by 1.6 V or leave floating when not in use. |
| 11 | SS | input | Soft-start control pin; leave open for default soft-start or connect external capacitor to ground to enable RC-delay soft-start circuit. |
| 12 | EN | input | Enable control pin; logic high enables device operation, logic low disables device. |
| 13 | IN | power_in | Unregulated supply voltage input pin; connect input capacitor to this pin. |
| 14 | IN | power_in | Unregulated supply voltage input pin; connect input capacitor to this pin. |
| 15 | OUT | power_out | Regulated output voltage pin; minimum 4.7-μF capacitance required for stability. |
| 16 | OUT | power_out | Regulated output voltage pin; minimum 4.7-μF capacitance required for stability. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
