TPS79501DCQR from Texas Instruments, in a SOT-223-6. 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 | EN | input | Enable input; drive high to enable regulator, low for shutdown mode; threshold voltages 0.85×VIN high and 0.425 low (new chip) or 1.7V and 0.7V (old chip). |
| 2 | IN | power_in | Input power supply; operational range 2.7 to 5.5V (old chip) or 2.7 to 6.0V (new chip); requires 2.2µF minimum input capacitor. |
| 3 | GND | power_in | Regulator ground; also on pin 6; connect to large area ground plane for improved thermal performance. |
| 4 | OUT | power_out | Regulated output voltage 1.225V to 5.5V for TPS79501 adjustable; requires 1µF minimum ceramic output capacitor for stability. |
| 5 | FB | input | Feedback input for adjustable output; external resistor divider sets output voltage with reference voltage 1.225V; bias current 1µA. |
| 6 | GND | power_in | Regulator ground; also on pin 3; connect to large area ground plane for improved thermal performance. |
