LM1117F-3.3

HTC Korea TAEJIN Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89

LM1117F-3.3 from HTC Korea TAEJIN Tech, in a SOT-89. 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 The pin is labeled Adjustable/Ground in the pin description table; on the fixed 3.3V device it serves as the ground return.
2 VOUT power_out Regulated output for the 3.3V fixed version, specified at 3.267V to 3.333V at 10mA and 3.234V to 3.366V over 0 to 1A and 0 to 125°C junction, and an output capacitor of 10µF or larger is needed for stability.
3 VIN power_in Input voltage pin with a maximum DC input voltage of 20V (absolute maximum) and a stated operating input voltage of 12V.
