LR8323B-T30

LR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L

LR8323B-T30 from LR, in a SOT-23-5L. 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 VIN power_in Input supply pin, rated up to 24V operating (32V absolute max); needs a ceramic bypass capacitor of at least 1uF close to the pin.
2 GND power_in Ground pin; use a large copper ground area for better noise immunity and heat dissipation.
3 CE input Chip enable input; enable turn-on voltage is 0.7V min to 1.2V max, and VCE=0V shuts the regulator down with shutdown current of ±1uA max.
4 NC unconnected No internal connection.
5 VOUT power_out Regulated 3.0V output (±1%) for the T30 option, up to 300mA, requiring an output capacitor of at least 1uF.
