LM1117IDTX-ADJ

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252

LM1117IDTX-ADJ from Texas Instruments, in a TO-252. 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 output Adjustment pin establishing 1.25V reference voltage between output and ADJ pin for programming output voltage from 1.25V to 13.8V using external resistor divider network.
2 VOUT power_out Regulated output voltage pin supplying up to 800mA continuous output current; requires minimum 10µF tantalum output capacitor for stability.
3 VIN power_in Unregulated input voltage pin requiring 1.4V minimum differential above output voltage, maximum 20V absolute rating to ground.
