TPS62202DBVR 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 | VI | power_in | Supply voltage input pin with recommended operating range of 2.5V to 6.0V. |
| 2 | GND | power_in | Ground reference pin. |
| 3 | EN | input | Enable input pin; pulling low forces device into shutdown mode, pulling high enables normal operation; must not float. |
| 4 | FB | input | Feedback input pin for output voltage regulation; connect directly to output for fixed versions or to resistor divider network for adjustable versions. |
| 5 | SW | output | Switch node output pin connected to internal MOSFET switches; connect external inductor to this pin for energy transfer during step-down conversion. |
