LM1117GS-2.5

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

LM1117GS-2.5 from HTC Korea TAEJIN Tech, in a SOT-223-3L. 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 ADJ/GND power_in On the fixed LM1117GS-2.5 this pin is the ground return, since the datasheet labels it Adjustable/Ground and the ADJ function applies only to the adjustable version.
2 VOUT power_out Regulated 2.5V output (2.450V to 2.550V over 0 to 125°C for 0 to 1A load), with a 10µF or larger output capacitor required for stability and a 1A current limit.
3 VIN power_in Input voltage pin with a 12V operating input limit and a 20V absolute maximum input voltage, needing about 1.2V of dropout at 1A.
