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. |
