LW5212N11E

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

LW5212N11E 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; the recommended VOUT pin voltage range is 0.8V to 5.0V, and this LW5212N11E is the 1.2V option, with output current rated 0 to 500mA.
2 GND power_in Ground reference pin, listed on the datasheet as '2,E-PAD' so the exposed pad is also GND; the layout guidance is to connect separate VIN and VOUT ground planes only at this GND pin.
3 EN input Chip enable input; the datasheet gives VENH min 1.5V and VENL max 0.5V, with the EN pin voltage recommended range 0 to 6.0V.
4 VIN power_in Power supply input with recommended range 1.5V to 6.0V and absolute maximum rating -0.3V to 7.0V.
5 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
