MIC2296YD5-TR from Microchip Tech, in a TSOT-23-5. 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 | SW | passive | Switch node connected to the internal power bipolar collector; rated -0.3V to 34V with 1.2A typical switch current limit. |
| 2 | GND | power_in | Ground return pin. |
| 3 | FB | input | Feedback input, 1.24V output voltage sense node with VOUT = 1.24V(1 + R1/R2). |
| 4 | EN | input | Enable input where logic high enables the regulator and logic low shuts it down. |
| 5 | VIN | power_in | Supply input, 2.5V to 10V input voltage. |
