LM1085IT-ADJG

HANSCHIP semiconductor · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220-3

LM1085IT-ADJG from HANSCHIP semiconductor, in a TO-220-3. 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 ADJ input Adjust pin of the LM1085-ADJ (labelled ADJ/GND; GND on fixed versions), which sets the output through the R1/R2 divider against the 1.25V reference and draws 40 µA typ (90 µA max) adjust current.
2 VOUT power_out Regulated output (also connected to the tab), supplying up to 3A with 1.5V max dropout at 3A and requiring an output capacitor for stability (22µF tantalum or 150µF aluminum).
3 VIN power_in Input voltage pin, absolute maximum 15V, with at least 1.5V input-to-output differential needed at 3A load.
