S-19212D33A-M5T1U from ABLIC, in a SOT-23-5. 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 | VIN | power_in | Input voltage pin; the input operates from 3.0 V to 36 V, with absolute maximum VSS − 0.3 V to VSS + 45 V. |
| 2 | VSS | power_in | GND pin, the regulator ground reference. |
| 3 | NC | unconnected | No connection; the pin is electrically open and may be connected to the VIN pin or the VSS pin. |
| 4 | ON / OFF | input | Active-high ON/OFF pin for the D type, with input voltage "H" (VSH) of 2.0 V min. and "L" (VSL) of 0.8 V max. |
| 5 | VOUT | power_out | Regulated output voltage pin, 3.3 V ± 2.0% for this variant, capable of 250 mA output at VIN ≥ VOUT(S) + 2.0 V. |
