LDK320AM-R 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, operating range 2.5 V to 18 V. |
| 2 | GND | power_in | Ground reference. |
| 3 | EN | input | Enable control digital input; logic low (0.4 V) initiates shutdown mode consuming <1 μA, logic high (1.2 V) activates the regulator. |
| 4 | ADJ | output | Adjustable reference voltage output at 1.185 V typical with ±0.5% accuracy at 25°C for external resistive divider feedback network. |
| 5 | OUT | output | Regulated output voltage capable of supplying up to 200 mA. |
