TPS79301DBVR from Texas Instruments, in a SOT-23-6. 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 | Input supply to the regulator. Recommended operating range 2.7 V to 5.5 V; absolute maximum 6 V. Requires a minimum 0.1 µF (typ 1 µF) input capacitor. |
| 2 | GND | power_in | Regulator ground; all voltages are referenced to this pin. |
| 3 | EN | input | Active-high enable input. Driving EN high turns on the regulator; driving it low puts the device in shutdown (<1 µA). Can be tied to IN if unused. VEN range 0 to VIN, absolute max 6 V. |
| 4 | NR | passive | Noise-reduction pin. An external capacitor (0 to 10 nF) from this pin to GND filters internal bandgap noise, improving PSRR and lowering output noise. Leave open if not used. |
| 5 | FB | input | Feedback input for the adjustable-voltage version. Connect to an external resistor divider from OUT to set VOUT = VFB × (1 + R1/R2), with VFB ≈ 1.22 V and lower resistor R2 ≈ 30.1 kΩ recommended. |
| 6 | OUT | power_out | Regulated output. Delivers up to 200 mA with ~112 mV dropout at 200 mA. Requires a 2.2 µF (min) to 10 µF ceramic output capacitor for stability. |
