MIC5203-3.3YM5-TR from Microchip Tech, in a SOT-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 | IN | power_in | Supply input; operating input voltage range is 2.5V to 16V. |
| 2 | GND | power_in | Ground. |
| 3 | EN | input | Enable input, TTL/CMOS compatible: logic high (above 2.0V) = enabled; logic low (below 0.6V) or open = shutdown. |
| 4 | NC | unconnected | Not internally connected. |
| 5 | OUT | power_out | Regulator output; typically requires only 0.47µF of output capacitance for stability. |
