Lewa Micro · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L
LW5433A23E from Lewa Micro, in a SOT-23-5L. 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 pin (1.9 V to 5.5 V); use the recommended or larger ceramic input capacitor placed as close to the device as possible. |
| 2 | GND | power_in | Ground pin. |
| 3 | EN | input | Enable pin: drive above VEN(HI) to turn the regulator on, and drive below VEN(LO) to put the LDO into shutdown mode. |
| 4 | NC | unconnected | No internal connection; the datasheet says to ground this pin for better thermal performance. |
| 5 | VOUT | power_out | Regulated output (1.2 V to 5.0 V) that needs a low-ESR capacitor, using the nominal recommended value or larger from OUT to GND; an internal pulldown discharges OUT in shutdown. |
