L5150BNTR from STMicroelectronics, in a SOT-223-4. 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 | VS | power_in | Supply voltage input rated 5.6V to 40V with maximum line regulation of 40mV. |
| 2 | GND | power_in | Ground reference. |
| 3 | Vo | output | 5V regulated output with ±2% tolerance and 150mA maximum output current (current limiting at 0.28A to 0.66A); requires 220nF ceramic capacitor to GND for stability. |
| 4 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
