TPS78633DCQR 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; logic high (>1.7 V) enables regulator, logic low (<0.7 V) shuts down regulator; quiescent current ±1 μA at VEN = 0 V. |
| 2 | IN | power_in | Input supply voltage with recommended operating range 2.7-5.5 V; dropout voltage 340-510 mV at 1.5 A output current for TPS78633. |
| 3 | GND | power_in | Regulator ground connection. |
| 4 | OUT | output | Regulated output voltage 3.3 V ±2% for TPS78633 fixed version, supporting 0-1.5 A maximum continuous output current. |
| 5 | NR | passive | Noise-reduction filter pin for fixed versions; external bypass capacitor (≤0.1 μF) connected to NR pin creates low-pass filter with internal 250 kΩ resistor to reduce voltage reference noise. |
| 6 | GND | power_in | Regulator ground connection and thermal dissipation path to printed circuit board. |
