LR8323B-T25 from LR, 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 | VIN | power_in | Input supply pin, rated up to 24 V (absolute maximum 32 V), and a ceramic input bypass capacitor of at least 1 µF is recommended. |
| 2 | GND | power_in | Ground reference pin; all datasheet voltages are referenced to GND. |
| 3 | CE | input | Chip enable (ON/OFF) control pin; the datasheet tests shutdown current with VCE = 0 V, but gives no logic threshold levels. |
| 4 | NC | unconnected | No internal connection. |
| 5 | VOUT | power_out | Regulated fixed output of 1.2 V to 5 V (T25 variant is 2.5 V nominal, ±1% accuracy), with a ceramic output capacitor of at least 1 µF required and up to 300 mA output current. |
