TPS7A8300RGWR from Texas Instruments, in a QFN-20-EP(5x5). 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 | OUT | output | Regulated output pin; 22-μF or larger ceramic capacitor required for stability. |
| 2 | SNS | input | Output voltage sense input pin; connect only if ANY-OUT feature is used. |
| 3 | FB | input | Output voltage feedback pin connected to error amplifier; 10-nF feed-forward capacitor from FB to OUT recommended for low-noise applications. |
| 4 | PG | tri_state | Active-high power-good open-drain output indicating when output voltage reaches 89% of target. |
| 5 | 50mV | input | Output voltage setting pin; connect to ground to increase output voltage by 50mV or leave floating. |
| 6 | 100mV | input | Output voltage setting pin; connect to ground to increase output voltage by 100mV or leave floating. |
| 7 | 200mV | input | Output voltage setting pin; connect to ground to increase output voltage by 200mV or leave floating. |
| 8 | GND | power_in | Ground pin. |
| 9 | 400mV | input | Output voltage setting pin; connect to ground to increase output voltage by 400mV or leave floating. |
| 10 | 800mV | input | Output voltage setting pin; connect to ground to increase output voltage by 800mV or leave floating. |
| 11 | 1.6V | input | Output voltage setting pin; connect to ground to increase output voltage by 1.6V or leave floating. |
| 12 | BIAS | power_in | BIAS supply voltage pin for use when 1.1V ≤ VIN ≤ 1.4V; connect 10-µF capacitor between this pin and ground. |
| 13 | NR/SS | input | Noise-reduction and soft-start pin; connect external capacitor to ground to reduce reference voltage noise and enable soft-start function. |
| 14 | EN | input | Enable pin; logic high enables device, logic low disables device. |
| 15 | IN | power_in | Input supply voltage pin; 10-μF input ceramic capacitor required. |
| 16 | IN | power_in | Input supply voltage pin; 10-μF input ceramic capacitor required. |
| 17 | IN | power_in | Input supply voltage pin; 10-μF input ceramic capacitor required. |
| 18 | GND | power_in | Ground pin. |
| 19 | OUT | output | Regulated output pin; 22-μF or larger ceramic capacitor required for stability. |
| 20 | OUT | output | Regulated output pin; 22-μF or larger ceramic capacitor required for stability. |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
