78L24 pdf datasheet (Multi-Cel

These voltage regulators are monolithic integrated circuits designed
as fixed–voltage regulators for a wide variety of applications
including local, on–card regulation. These regulators employ internal
current limiting, thermal shutdown, and safe–area compensation. With
adequate heatsinking they can deliver output currents in excess of
1.0 A. Although designed primarily as a fixed voltage regulator, these
devices can be used with external components to obtain adjustable
voltages and currents.
• Output Current in Excess of 1.0 A
• No External Components Required
• Internal Thermal Overload Protection
• Internal Short Circuit Current Limiting
• Output Transistor Safe–Area Compensation
• Output Voltage Offered in 2% and 4% Tolerance
• Available in Surface Mount D2PAK, DPAK and Standard 3–Lead Transistor Packages
