LW5928N23C

Lewa Micro · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23

LW5928N23C from Lewa Micro, in a SOT-23. 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; in the SOT23 package this is the only ground connection, and the datasheet recommends separate VIN and VOUT ground planes joined only at the GND pin.
2 VOUT power_out Regulated output pin that needs a low-ESR capacitor, at least the nominal recommended value, from OUT to GND; an internal pulldown discharges OUT when the regulator is in shutdown (VEN < VEN(LOW)), with output current rated 0 to 400 mA.
3 VIN power_in Input supply pin with a recommended operating range of 1.6 V to 7.0 V, which needs the recommended or larger ceramic input capacitor to ground placed as close to the pin as possible.
