LR8203A-T30

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

LR8203A-T30 from LR, in a SOT-23-3L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground reference for the regulator. Connect to the system ground plane; return path for input and output currents.
2 VOUT power_out Regulated output pin. Delivers a fixed 3.0 V (T30 option) at up to 300 mA typical. Requires an output capacitor (C_OUT = 1 uF typical) to GND for stability.
3 VIN power_in Unregulated input supply. Operating range up to 6.5 V (absolute max 9 V). Bypass with a 1 uF input capacitor (C_IN) to GND close to the pin.
