LDLN025M12R

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.
