HX1001-AEC from SHOUDING, in a SOT-23-5L. 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 | ON/OFF control, high enable: above 1.5V enables the part, below 0.6V shuts it down (<1μA supply current); do not leave floating. |
| 2 | GND | power_in | Ground pin. |
| 3 | SW | passive | Switch node connection to the inductor, joining the drains of the internal main and synchronous power MOSFET switches (SW pin current max 1.3A). |
| 4 | VIN | power_in | Main supply pin (2.5V to 5.5V for HX1001-AEC), to be closely decoupled to GND with a recommended 10μF ceramic capacitor. |
| 5 | VOUT/FB | input | Feedback pin: in the adjustable version (HX1001-AEC) it receives feedback from an external resistive divider setting VOUT = 0.6V • [1 + (R1/R2)], regulated at 0.6V. |
