STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
LDK320AM50R 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 voltage supply with operating range 2.5 V to 18 V and typical dropout voltage of 100 mV at 100 mA output current. |
| 2 | GND | power_in | Common ground reference. |
| 3 | EN | input | Enable pin logic input with logic low at ≤0.4 V for shutdown mode and logic high at ≥1.2 V for active mode. |
| 4 | ADJ/NC | unconnected | Not connected on fixed output version; adjustable pin on adjustable variants only. |
| 5 | OUT | power_out | Fixed 5 V output voltage with ±0.5% tolerance at 25°C and ±1.5% across -40 to 125°C, output current capability up to 200 mA. |
