SGM2028-3.3YN5G
SGMICRO · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
SGM2028-3.3YN5G 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 | IN | power_in | Regulator input supply, which can range from 2.5V to 5.5V and should be bypassed with a 1µF capacitor to GND. |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | EN | input | Shutdown input where a logic low reduces the supply current to 10nA, and it should be connected to IN for normal operation. |
| 4 | BP | passive | Reference-noise bypass for the fixed-voltage version, which should be bypassed with a low-leakage 0.01µF ceramic capacitor to reduce output noise. |
| 5 | OUT | power_out | Regulator output that delivers up to 500mA guaranteed output current. |
