LDLN025PU12R

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

LDLN025PU12R from STMicroelectronics, in a DFN-4(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 output LDO output voltage supporting up to 250mA output current; accuracy ±2% for VOUT≥1.8V or ±4% for VOUT<1.8V.
2 GND power_in Ground.
3 EN input Enable input with 1MΩ internal pull-down; set high (≥1.2V) to enable or low (≤0.4V) to disable the device.
4 VIN power_in Supply voltage input with operating range 1.5V to 5.5V.
5 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
