LM1117DT-ADJ

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

LM1117DT-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 passive Adjust pin of the adjustable version that sets the output voltage through the external resistor divider from a 1.25 V reference, with ADJ current typically 60 µA and able to withstand ±25 V transients relative to VOUT without damage.
2 VOUT output Regulator output pin (also connected to the TAB); a tantalum output capacitor of at least 10 µF with ESR between 0.3 Ω and 22 Ω is required for stability, and 22 µF is needed when a CADJ bypass capacitor is used.
3 VIN power_in Regulator input pin, with an absolute maximum VIN-to-GND of 20 V and a recommended input voltage of up to 15 V.
