AP78L12
12V OUTPUT 3-TERMINAL POSITIVE REGULATORS
Features
General Description
• 12.0V output voltage with tolerances of ±5% over the
temperature range
• Output current in excess of 100mA
• Internal thermal overload protection
• Output transistor safe area protection
• Internal short circuit current limiting
• No external components
• Available in plastic TO92-3L and plastic SOP-8L low
profile packages
• Lead-free Package: TO92-3L (Note 1)
• SOP-8L: Available in “Green” Molding Compound
(No Br, Sb) (Note 2)
• Lead Free Finish / RoHS Compliant (Note 3)
The AP78L12 of three terminal positive regulators is available
with fixed output voltages making them useful in a wide range of
applications. These regulators can provide local on card
regulation, eliminating the distribution problems associated with
single point regulation. The voltages available allow the AP78L12
to be used in logic system, instrumentation, HiFi, and other solid
state electronic equipment.
The AP78L12 is available in the plastic TO92-3L package, the
plastic SOP-8L package using industrial standard 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.
Applications
Well suited for a wide range of applications, such as:
• Lighting Ballast
• STB
• Power supply
• Audio Equipment
