MAX40203AUK+T from Analog Devices Inc Maxim Integrated, 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 | VDD | power_in | Supply voltage input and diode anode, operating range 1.2V to 5.5V, source of forward current when enabled. |
| 2 | GND | power_in | Ground reference and power supply return. |
| 3 | EN | input | Active-high enable input with internal weak pullup, accepts 0V to 5.5V regardless of VDD, controls forward current path. |
| 4 | N.C. | unconnected | No connection, not internally connected. |
| 5 | OUT | output | Regulated current output and diode cathode, maximum 1A continuous current in SOT package, internal supply source when VOUT > VDD. |
