LM1117S-1.2

HTC Korea TAEJIN Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-3

LM1117S-1.2 from HTC Korea TAEJIN Tech, in a SOT-223-3. 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/GND power_in Adjustable/ground pin; the datasheet lists its function only as 'Adjustable / Ground' and gives no separate electrical limit for this pin.
2 VOUT power_out Regulated output pin; for the 1.2 V fixed version the output is 1.200 V typical at 10 mA, and 1.152 V to 1.248 V over VIN = 2.7 V to 12 V, IO = 0 mA to 1 A, TJ = 0 to 125 °C.
3 VIN power_in Input voltage pin; operating input voltage is up to 12 V, and the absolute maximum DC input voltage is 20 V.
