AMS1117-1.2 SOT-89

Slkor SLKORMICRO Elec · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

AMS1117-1.2 SOT-89 from Slkor SLKORMICRO Elec, in a SOT-89-3. 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 power_in Ground reference pin (labelled ADJ/GND; on the fixed 1.2V version it is ground, with the ground pin connectable to the low side of the load).
2 VOUT power_out Regulated 1.2V output (1.176V to 1.224V) delivering up to 0.8A, requires an output capacitor of at least 10uF tantalum with ESR not exceeding 0.5 ohm.
3 VIN power_in Input supply pin, maximum input voltage 18V, with a 10uF tantalum input bypass capacitor recommended.
