SGM2036-2.5YN5G 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 | IN | power_in | Input voltage supply pin, operating range 1.6V to 5.5V; use a 1μF or larger ceramic capacitor from IN to ground placed as close as possible to the pin. |
| 2 | GND | power_in | Ground pin. |
| 3 | EN | input | Enable pin: drive high (above 1.5V) to turn the regulator on and low (below 0.4V) to turn it off, and pull it high through an external resistor to IN if the pin is not used. |
| 4 | BP | passive | Reference-noise bypass pin (fixed voltage version only); an external CBP capacitor placed very close to the pin reduces output noise and improves PSRR. |
| 5 | OUT | power_out | Regulator output pin; use a ceramic capacitor of 0.5μF to 10μF placed as close as possible to the OUT pin for decoupling. |
