SE5218ALG-LF
Seaward Elec · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
SE5218ALG-LF from Seaward Elec, 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 | Regulator input supply, operating range +2.8V to +5.5V (absolute maximum 6V), with an input capacitor of at least 1μF required. |
| 2 | GND | power_in | Ground; the output capacitor connects directly between VOUT and GND. |
| 3 | ENABLE | input | Enable input, output turns on above 1.6V (logic high) and off below 0.4V (logic low), with voltage range -0.3V to VIN. |
| 4 | NC | unconnected | No connect pin with no internal function stated. |
| 5 | VOUT | power_out | Fixed regulated output (3.3V for SE5218ALG-LF), needing at least 1μF output capacitor placed within 1 cm of the pin for stability. |
