LDLN025M33R from STMicroelectronics, 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 | LDO supply voltage input; operating range 1.5 V to 5.5 V, maximum rating -0.3 to 7 V. |
| 2 | GND | power_in | Ground connection. |
| 3 | EN | input | Enable input; set high (VIH = 1.2 V minimum) to turn on device, set low (VIL = 0.4 V maximum) to turn off device; internally pulled down via 1 MΩ resistor. |
| 4 | NC | unconnected | Not internally connected; can be connected to GND. |
| 5 | VOUT | output | LDO regulated output voltage 3.3 V ±2.0% over -40 °C to 125 °C, maximum output current 250 mA, typical dropout voltage 120 mV at 250 mA load. |
