TPS7A7300RGWR from Texas Instruments, in a VQFN-20(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 | power_out | Regulated output pin that requires a 4.7-µF or larger capacitance for stability, with COUT specified from 4.7 µF to 200 µF. |
| 2 | SNS | input | Output voltage sense input used with the FB pin in the user-configurable and traditional adjustable output voltage configurations. |
| 3 | FB | input | Output voltage feedback pin connected to the error amplifier, which requires a 220-pF ceramic capacitor from FB to OUT. |
| 4 | PG | output | Active-high open-drain power-good output that indicates when the output reaches 90% of the target, with a sink current limit of 5 mA and a pullup voltage up to 6.5 V. |
| 5 | 50mV | input | Output voltage setting pin that must be connected to ground or left floating, and connecting it to ground increases VOUT by 50 mV. |
| 6 | 100mV | input | Output voltage setting pin that must be connected to ground or left floating, and connecting it to ground increases VOUT by 100 mV. |
| 7 | 200mV | input | Output voltage setting pin that must be connected to ground or left floating, and connecting it to ground increases VOUT by 200 mV. |
| 8 | GND | power_in | Ground pin. |
| 9 | 400mV | input | Output voltage setting pin that must be connected to ground or left floating, and connecting it to ground increases VOUT by 400 mV. |
| 10 | 800mV | input | Output voltage setting pin that must be connected to ground or left floating, and connecting it to ground increases VOUT by 800 mV. |
| 11 | 1.6V | input | Output voltage setting pin that must be connected to ground or left floating, and connecting it to ground increases VOUT by 1.6 V. |
| 12 | NC | unconnected | Not internally connected; this pin and the thermal pad must be connected to a large-area ground plane. |
| 13 | SS | passive | Soft-start pin that gives the default soft start when left open, or forms an RC delay with an external capacitor to ground when one is connected. |
| 14 | EN | input | Enable pin where logic high enables the device and logic low disables it, with VEN specified from 0 V to 6.5 V. |
| 15 | IN | power_in | Unregulated supply voltage pin with an input capacitor connected to it, with VIN specified from 1.425 V to 6.5 V. |
| 16 | IN | power_in | Unregulated supply voltage pin with an input capacitor connected to it, with VIN specified from 1.425 V to 6.5 V. |
| 17 | IN | power_in | Unregulated supply voltage pin with an input capacitor connected to it, with VIN specified from 1.425 V to 6.5 V. |
| 18 | GND | power_in | Ground pin. |
| 19 | OUT | power_out | Regulated output pin that requires a 4.7-µF or larger capacitance for stability, with COUT specified from 4.7 µF to 200 µF. |
| 20 | OUT | power_out | Regulated output pin that requires a 4.7-µF or larger capacitance for stability, with COUT specified from 4.7 µF to 200 µF. |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
