LM1086IT-3.3G

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

LM1086IT-3.3G 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 GND/ADJ power_in Ground reference pin, which doubles as the adjust pin on the adjustable version (the fixed-voltage LM1086IT-3.3G uses it as ground).
2 VOUT power_out Regulated output voltage; for the LM1086-3.3 fixed version the output is 3.3 V, and the output must be bypassed with at least 22 µF tantalum for the adjustable version (smaller capacitors may be used on fixed versions).
3 VIN power_in Input supply voltage; the recommended input voltage is 15 V maximum and the absolute maximum input voltage is 20 V.
