AP78L12 12V OUTPUT 3-TERMINAL POSITIVE REGULATORS Features • • • • • • • • • • 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) General Description 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 Ordering Information AP 78 L 12 X X X Package V : TO92-3L S : SOP-8L Lead Free L : Lead Free (Note 1) G : Green (Note 2) Packing -A : Ammo Box -13 : Taping Note: 1.

Function Description Introduction The AP78L12 fixed-mode 12V output voltage regulator is a three terminal device. The AP78L12 fixed voltage regulator series has built-in thermal overload protection which prevents the device from being damaged due to excessive junction temperature. The regulators also contain internal short-circuit protection which limits the maximum output current, and safe-area protection for the pass transistor which reduces the short-circuit current as the voltage across the pass transistor is increased.
