HTC Korea TAEJIN Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOP-8

LM78L05D from HTC Korea TAEJIN Tech, in a SOP-8. 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 VOUT power_out Regulated +5.0V output. Delivers up to 100mA with internal current limit at ~250-300mA. Recommend a 0.1uF bypass capacitor to GND close to this pin for stability.
2 GND power_in Device ground / common return. Tie to system ground; also acts as the thermal reference for the SOP-8 package.
3 GND power_in Additional ground pin, internally tied to pin 2. Connect to system ground plane for improved thermal dissipation.
4 NC unconnected No internal connection. Leave floating or tie to ground per PCB layout preference.
5 NC unconnected No internal connection. Leave floating or tie to ground per PCB layout preference.
6 GND power_in Additional ground pin, internally tied to pin 2. Connect to system ground plane for improved thermal dissipation.
7 GND power_in Additional ground pin, internally tied to pin 2. Connect to system ground plane for improved thermal dissipation.
8 VIN power_in Unregulated positive input voltage. Recommended operating range 7V to 20V for the 5V version (absolute maximum 30V). Dropout voltage ~1.7V typical. Requires a 0.33uF bypass capacitor to GND close to this pin.
