LR8341A-T27

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

LR8341A-T27 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 for the regulator; all voltages are specified relative to GND.
2 VOUT power_out Regulated 2.7V output (±1% at VIN=VOUT+2V, IOUT=10mA) delivering 100mA, needs at least 1uF ceramic output capacitor, short-circuit current limited to 15mA.
3 VIN power_in Input supply up to 40V operating (55V absolute maximum), needs at least 1uF ceramic bypass capacitor close to the pin.
