# LW5215A23E

**Lewa Micro** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L

LW5215A23E 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 pin; use the recommended value or a larger ceramic capacitor from IN to ground, placed as close to the device as possible, with VIN specified at 1.5 V to 6.0 V. |
| 2 | GND | power_in | Ground pin. |
| 3 | EN | input | Enable pin; drive above VEN(HI) (1.5 V typ/min per the electrical table) to turn the regulator on and below VEN(LO) (0.5 V) to put the LDO into shutdown, with EN pin voltage rated 0 V to 6.0 V. |
| 4 | NC | unconnected | No internal connection; the datasheet says to ground this pin for better thermal performance. |
| 5 | VOUT | power_out | Regulated output pin, with output voltage 1.2 V to 5.0 V and an internal pulldown that discharges OUT in shutdown; use a low-ESR capacitor of at least 1 µF from OUT to GND. |
