LM317AEMPRG from HANSCHIP semiconductor, in a SOT-223. 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 | ADJUST | passive | The adjust pin is the reference divider node; the datasheet states the adjust current is controlled below 100 µA (typical 50 µA, change 0.2 to 5 µA over line and load) and is held constant, so it is connected to ground through R2 to set the output voltage. |
| 2 | VOUT | power_out | The regulated output; the datasheet rates the maximum output current at 1.5 A, with minimum load current of 3.5 to 10 mA needed to maintain regulation. |
| 3 | Vin | power_in | The unregulated input supply; the input-to-output differential must stay within 3 V to 40 V (absolute maximum 40 V). |
