LW5233N11E

Lewa Micro · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DFN-4L(1x1)

LW5233N11E from Lewa Micro, in a DFN-4L(1x1). 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 VOUT power_out Regulated output pin that needs a low-ESR capacitor of at least 1µF from OUT to GND for stability, with an internal pulldown discharging OUT in shutdown, and the output is selectable from 1.2V to 5.0V.
2 GND power_in Ground pin that should be connected to the GND plane, and the thermal pad is electrically connected to this node for improved thermal performance.
3 EN input Enable pin that must be driven above VENH (1.5V min) to turn on the regulator and below VENL (0.5V max) to put the LDO into shutdown, with an absolute maximum of -0.3 to 7.0V.
4 VIN power_in Input supply pin with a recommended operating range of 1.5V to 6.0V, which should use the recommended value or larger ceramic capacitor from IN to ground placed as close to the device as possible.
5 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
