SNVS754I – JANUARY 2000 – REVISED APRIL 2013
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
DESCRIPTION (CONTINUED)
The LM78LXX is available in the plastic TO-92 (LP) package, the SOIC-8 (D) package and a chip sized package
(8-Bump DSBGA) using TI's DSBGA package technology. With adequate heat sinking the regulator can deliver
100mA output current. Current limiting is included to limit the peak output current to a safe value. Safe area
protection for the output transistors is provided to limit internal power dissipation. If internal power dissipation
becomes too high for the heat sinking provided, the thermal shutdown circuit takes over preventing the IC from
overheating.
