Lewa Micro · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3L
LW5915N23D from Lewa Micro, in a SOT-23-3L. 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 | GND | power_in | Ground pin; the datasheet recommends separate ground planes for VIN and VOUT, with each connected only at the GND pin. |
| 2 | VOUT | power_out | Regulated output voltage pin (0.8 V to 5.0 V output range); connect a low-ESR capacitor, using the nominal recommended value or larger from OUT to GND for best transient response, and an internal pulldown discharges OUT in shutdown (VEN < VEN(LOW)). |
| 3 | VIN | power_in | Input pin with an operating supply range of 1.6 V to 7.0 V; use the recommended or larger ceramic capacitor from IN to ground, placed as close to the device as possible. |
