LR8341A-M30

LR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

LR8341A-M30 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; all voltages are specified relative to GND.
2 VIN power_in Input supply, operating up to 40V (absolute maximum 55V), requires an input capacitor of at least 1uF ceramic placed close to the pin.
3 VOUT power_out Fixed 3.0V regulated output for the M30 variant, 100mA typical output current, requires an output capacitor of at least 1uF and has short-circuit protection of 15mA.
