LM39100S-5.0

HTC Korea TAEJIN Tech LM39100S 5 0 · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

LM39100S-5.0 from HTC Korea TAEJIN Tech LM39100S 5 0, in a SOT-223. 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 VIN power_in Input supply. Operating range +2.25V to +16V (absolute max +20V). Bypass with a ceramic capacitor close to the pin.
2 GND power_in Device ground. Tied to the SOT-223 thermal tab for heat-sinking to the PCB copper.
3 VOUT power_out Regulated 5.0V fixed output, 1A minimum guaranteed. Requires an output capacitor for stability and transient response.
