LR8342A-T50

LR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3L

LR8342A-T50 from LR, in a SOT-23-3L. 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 pin; all voltages in the datasheet are referenced to GND unless otherwise noted.
2 VOUT power_out Regulated output voltage pin, rated for a maximum output current of 250 mA with ±2% output voltage tolerance.
3 VIN power_in Input voltage pin, with a maximum input supply voltage of 45 V relative to GND per the absolute maximum ratings.
