LR6206A-T28

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

LR6206A-T28 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 VSS power_in Ground (reference) pin; the datasheet states that all voltages are measured relative to VSS unless otherwise noted.
2 VOUT power_out Regulated 2.8 V output for the LR6206A-T28 (±2%), rated for 300 mA typical and 450 mA maximum output current, and requires a ceramic output capacitor of at least 1 uF.
3 VIN power_in Unregulated input supply; maximum input voltage is 6.5 V in operation (9 V absolute maximum), and at least a 1 uF ceramic bypass capacitor is recommended.
