SGM2202-3.3YN5G from SGMICRO, 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 supply voltage pin; the datasheet recommends a 1μF or larger ceramic capacitor from VIN to ground placed as close as possible to the pin, and the recommended input voltage range is 2.7V to 36V. |
| 2 | GND | power_in | Ground pin. |
| 3 | EN | input | Enable pin: drive high to turn the regulator on and low to turn it off, and it must be connected to VIN if enable functionality is not used. |
| 4 | BP | passive | Reference-noise bypass pin; an external CBP capacitor reduces output noise and should be placed very close to the pin for high PSRR. |
| 5 | VOUT | power_out | Regulator output pin; the datasheet recommends an effective output capacitance of 1μF to 10μF located very close to this pin. |
