Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | IN | power_in | Regulator input voltage. Operating range 2.7V to 5.5V (absolute maximum -0.3V to 6V old chip / 6.5V new chip). A 0.1µF to 1µF input capacitor is recommended. |+| 2 | GND | power_in | Regulator ground reference. |+| 3 | EN | input | Enable input. Drive logic high (0 to 5.5V range) to enable the regulator; drive logic low to place the device in shutdown mode. Used for power sequencing. |+| 4 | BYPASS/NC | passive | Old chip (BYPASS): external bypass capacitor to this pin works with an internal resistor to form a low-pass filter that further reduces regulator noise. New chip (NC): no connection, not internally connected - may be tied to GND to improve thermal performance or left floating. |+| 5 | FB | input | Feedback input voltage for the adjustable regulator (TPS79301-Q1). Connect to the tap of an external resistor divider from OUT to GND to set the output voltage (VFB ≈ 1.2246V nominal, output range VFB to 5V). |+| 6 | OUT | power_out | Regulated output. Sources up to 200mA continuous. Requires an output capacitor of 2.2µF (old chip) or 1µF (new chip) ceramic minimum for stability, up to 10µF (old) / 200µF (new). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-6 |+| Category | Power Management (PMIC) |+| Pins | 6 |++## Ordering variants++Same part, different packaging or reel option.++- `TPS79301DBVRG4Q1`+- `TPS79301DBVRG4Q1DBVT`++## CAD (KiCad official)++- Symbol: `TPS79301DBVRG4Q1`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/tps793-q1) (None pp, sha256 `7ea2cf405d5dd786`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
