LDK220M36R

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

LDK220M36R from STMicroelectronics, in a SOT-23-5. 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 with operating range 2.5 to 13.2 V and typical 100 mV dropout voltage at 100 mA load.
2 GND power_in Common ground reference.
3 EN input Logic-controlled enable input; active high (≥1.2 V), shutdown at low (≤0.4 V); input current 0.1 to 100 nA.
4 ADJ/NC unconnected Not connected on fixed output version; adjustable pin function not available on LDK220M36R.
5 OUT power_out Output voltage 3.6 V ±2.0% at 25°C with maximum 200 mA output current; requires 1 to 22 µF external capacitor.
