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. |
