# LR6302A33M

**LRC** · DC-DC Converters · SOT-23

LR6302A33M from LRC, in a SOT-23. 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 | VSS | power_in | Ground pin of the LR6302A (SOT-23-3, M suffix), the reference for all voltages and the return for the 1µF input and output capacitors. |
| 2 | VOUT | power_out | Regulated output delivering up to 300mA, with the output voltage range stated as 1.2V to 5V and a 1µF output capacitor required to ground for loop stability. |
| 3 | VIN | power_in | Power input with a recommended supply range of 2.5V to 18V (absolute maximum -0.3V to 24V), decoupled with a 1µF ceramic capacitor. |
