LM3480IM3-3.3

Texas Instruments LM3480IM3 3 3 NOPB · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23

LM3480IM3-3.3 from Texas Instruments LM3480IM3 3 3 NOPB, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT power_out Regulated output voltage pin. For the LM3480IM3-3.3 variant this pin sources a nominal 3.3 V (3.17 V to 3.43 V at 25°C) at up to 100 mA. Requires a minimum output capacitor of 0.1 µF for stability.
2 IN power_in Unregulated input voltage supply. Operates from VOUT + 1.5 V up to 30 V (35 V absolute maximum). Requires a minimum input capacitor of 0.1 µF for stability and transient performance.
3 GND power_in Common ground reference for both input and output. Ground pin current is typically 2 mA (no load) and up to 4 mA over temperature. Serves as the thermal path - connect to a ground plane to meet thermal requirements.
