TPS7A8300ARGRT 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 pin; requires 47µF or larger ceramic capacitor to ground for stability. |
| 2 | SNS | input | Output voltage sense input pin; connect to load-side output trace only if ANY-OUT feature is used. |
| 3 | FB | input | Feedback input to error amplifier; optional 10nF feed-forward capacitor from FB to OUT maximizes AC performance. |
| 4 | PG | output | Active-high open-drain power-good output; requires 10-100kΩ pull-up resistor. |
| 5 | 50mV | input | ANY-OUT voltage setting pin; connect to GND, SNS, or leave floating to set output with 50mV resolution. |
| 6 | 100mV | input | ANY-OUT voltage setting pin; connect to GND, SNS, or leave floating to set output with 100mV resolution. |
| 7 | 200mV | input | ANY-OUT voltage setting pin; connect to GND, SNS, or leave floating to set output with 200mV resolution. |
| 8 | GND | power_in | Ground pin; connect to ground plane, thermal pad, and pin 18 with low-impedance connection. |
| 9 | 400mV | input | ANY-OUT voltage setting pin; connect to GND, SNS, or leave floating to set output with 400mV resolution. |
| 10 | 800mV | input | ANY-OUT voltage setting pin; connect to GND, SNS, or leave floating to set output with 800mV resolution. |
| 11 | 1.6V | input | ANY-OUT voltage setting pin for TPS7A8300A; connect to GND, SNS, or leave floating for 1.6V resolution. |
| 12 | BIAS | power_in | Bias supply voltage input (3.0V to 6.5V); enables low-input, low-output operation; requires 1µF minimum capacitor to ground. |
| 13 | NR/SS | passive | Noise-reduction and soft-start pin; connect 10nF or larger capacitor to ground to reduce reference noise and enable soft-start. |
| 14 | EN | input | Enable control input; drive to logic high to enable device, logic low to disable; connect to IN or BIAS if not required. |
| 15 | IN | power_in | Input supply voltage (1.1V to 6.5V); requires 10µF or larger ceramic capacitor to ground. |
| 16 | IN | power_in | Input supply voltage; paralleled with pins 15 and 17 for improved current distribution. |
| 17 | IN | power_in | Input supply voltage; paralleled with pins 15 and 16 for improved current distribution. |
| 18 | GND | power_in | Ground pin; connect to ground plane, thermal pad, and pin 8 with low-impedance connection. |
| 19 | OUT | output | Regulated output pin; paralleled with pins 1 and 20 for improved current distribution to load. |
| 20 | OUT | output | Regulated output pin; paralleled with pins 1 and 19 for improved current distribution to load. |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
