STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L
LDLN025M12R 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 with operating range of 1.5 V to 5.5 V. |
| 2 | GND | power_in | Ground reference. |
| 3 | EN | input | Enable input; set high to turn on the device, low to turn off; internally pulled down via 1 MΩ resistor. |
| 4 | NC | unconnected | Not internally connected pin; can be connected to GND. |
| 5 | VOUT | power_out | LDO regulated output voltage with maximum output current of 250 mA and versions from 1 V to 5 V in 50 mV steps. |
