TPS7A8300ARGRR from Texas Instruments, in a VQFN-20-EP(3.5x3.5). 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 | OUT | output | Regulated output requiring 47-µF minimum ceramic capacitor to ground for stability. |
| 2 | SNS | input | Output voltage sense input connecting internal R1 resistor to output load side, use only with ANY-OUT feature or leave floating. |
| 3 | FB | input | Feedback pin connected to error amplifier; optional 10-nF feed-forward capacitor to OUT improves ac performance. |
| 4 | PG | tri_state | Open-drain power-good output indicating when output voltage reaches target threshold VIT(PG). |
| 5 | 50mV | input | ANY-OUT programmable voltage setting input; connect to GND, SNS, or leave floating to select output voltage. |
| 6 | 100mV | input | ANY-OUT programmable voltage setting input; connect to GND, SNS, or leave floating to select output voltage. |
| 7 | 200mV | input | ANY-OUT programmable voltage setting input; connect to GND, SNS, or leave floating to select output voltage. |
| 8 | GND | power_in | Ground pin requiring low-impedance connection to thermal pad and other ground pins. |
| 9 | 400mV | input | ANY-OUT programmable voltage setting input; connect to GND, SNS, or leave floating to select output voltage. |
| 10 | 800mV | input | ANY-OUT programmable voltage setting input; connect to GND, SNS, or leave floating to select output voltage. |
| 11 | 1.6V | input | ANY-OUT programmable voltage setting input; connect to GND, SNS, or leave floating to select output voltage. |
| 12 | BIAS | power_in | Bias supply input (3.0V to 6.5V) enabling low-input voltage operation; requires 1-µF minimum capacitor to ground. |
| 13 | NR/SS | passive | Noise-reduction and soft-start capacitor pin; external 10-nF minimum capacitor to ground reduces reference noise and enables soft-start. |
| 14 | EN | input | Enable input; logic high enables device, logic low disables; connect to IN or BIAS if unused. |
| 15 | IN | power_in | Input supply voltage pin (1.1V to 6.5V) requiring 10-µF minimum ceramic capacitor to ground for supply filtering. |
| 16 | IN | power_in | Input supply voltage pin (1.1V to 6.5V) requiring 10-µF minimum ceramic capacitor to ground for supply filtering. |
| 17 | IN | power_in | Input supply voltage pin (1.1V to 6.5V) requiring 10-µF minimum ceramic capacitor to ground for supply filtering. |
| 18 | GND | power_in | Ground pin requiring low-impedance connection to thermal pad and other ground pins. |
| 19 | OUT | output | Regulated output requiring 47-µF minimum ceramic capacitor to ground for stability. |
| 20 | OUT | output | Regulated output requiring 47-µF minimum ceramic capacitor to ground for stability. |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
