LM78M05CDT

HGSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2L

LM78M05CDT from HGSEMI, in a TO-252-2L. 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 Unregulated DC input voltage. For 5V output, maximum input is 35V; typical input range is 7 to 25V. A 0.33 µF input capacitor is recommended close to the pin.
2 GND power_in Common ground reference for input and output. Electrically connected to the exposed TAB of the TO-252-2 package, which also serves as the thermal path.
3 VOUT power_out Regulated +5V output, ±2% tolerance, capable of sourcing over 0.5 A with proper heatsinking. A 0.1 µF output capacitor is recommended for stability.
TAB GND power_in Metal tab on the back of the TO-252-2 package. Electrically tied to GND (pin 2) and serves as the primary thermal path (RthJC = 8 °C/W). Should be soldered to a copper pour for heat dissipation.
