TPS79301DBVRQ1 from Texas Instruments, in a SOT-23-6. 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 | IN | input | Device input; the datasheet specifies a recommended VIN range of 2.7 V to 5.5 V, with a 0.1 µF or larger ceramic input capacitor required for stability. |
| 2 | GND | power_in | Regulator ground pin; per the layout guidance it should be the only point where the ground planes connect. |
| 3 | EN | input | Active-high enable: driving EN above VEN(HI) enables the device and driving it below the maximum VEN(LOW) disables it; tie EN to IN if shutdown is not needed. |
| 4 | BYPASS | passive | On the old chip this pin is BYPASS, which connects through an internal 250 kΩ resistor to the voltage reference and forms a low-pass filter with an external bypass capacitor to reduce noise; on the new chip this pin is not internally connected and may be tied to ground for thermal performance or left floating. |
| 5 | FB | input | Feedback input for the adjustable device, used with external divider resistors R1 and R2 to set the output voltage relative to the internal reference VREF (1.225 V typical). |
| 6 | OUT | output | Regulated output that requires a stabilizing ceramic output capacitor of at least 2.2 µF (old chip) or 0.47 µF (new chip, minimum effective capacitance). |
