TPS73218DBVR from Texas Instruments, in a SOT-23-5. 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 power supply, operating voltage range 1.7V to 5.5V. |
| 2 | GND | power_in | Ground return connection. |
| 3 | EN | input | Enable input pin; VEN ≥1.7V (minimum) enables regulator, VEN ≤0.5V (maximum) places device in shutdown mode with quiescent current below 1µA. |
| 4 | NR | output | Noise reduction output pin for fixed-voltage versions; connect external 0.01µF capacitor from this pin to ground to filter internal bandgap reference noise and reduce output voltage noise. |
| 5 | OUT | power_out | Regulated output voltage, achieves stable operation without external output capacitor, maximum output current 250mA. |
