LDK120M18R

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

LDK120M18R 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 IN power_in Input supply voltage, rated 1.9 to 5.5 V operating range with absolute maximum -0.3 to 7 V
2 GND power_in Ground, common reference
3 EN input Logic control input; Low ≤ 0.4 V = shutdown mode, High ≥ 1.2 V = active mode
4 BYP passive Bypass capacitor connection for noise reduction on fixed version, maximum voltage 2 V, may be left floating if not used
5 OUT power_out Regulated output voltage providing 1.8 V ± 2.0% at 25 °C with guaranteed 200 mA output current capability
