LR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3
LR8341A-M50 from LR, in a SOT-89-3. 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 | GND | power_in | Ground reference for the regulator; all voltages are specified relative to GND. |
| 2 | VIN | power_in | Input supply pin accepting up to 40V (55V absolute maximum), requiring a ceramic bypass capacitor of at least 1uF. |
| 3 | VOUT | power_out | Fixed 5.0V regulated output (±2%) delivering 100mA, requiring an output capacitor of at least 1uF, with short-circuit protection limiting current to 15mA. |
