STLQ50C33R from STMicroelectronics, in a SC-70-5. 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 | N/C | unconnected | Not connected on the fixed-voltage version (STLQ50C33R); this pin is used as the ADJ feedback input only on the adjustable version. |
| 2 | GND | power_in | Ground pin; quiescent current of the fixed version is measured on this pin (3.5 µA typ at VI=5V, 4.1 µA typ at VI=12V). |
| 3 | N/C | unconnected | Not connected pin. |
| 4 | IN | power_in | Input voltage pin; accepts 2.3 V to 12 V (IO=20 mA) or 2.5 V to 12 V (IO=50 mA), absolute maximum -0.3 V to +14 V. |
| 5 | OUT | power_out | Regulated output voltage pin, nominal 3.3 V on this fixed version, supplying up to 50 mA with 0.4 V (typ) / 0.7 V (max) dropout at full load. |
