| Preliminary Datasheet 100mA POSITIVE VOLTAGE REGULATOR General Description The AS78LXX series are three terminal positive regulators designed for a wide variety of applications including local, on-card regulation. This series of regulators are complete with internal current limiting, thermal shutdown protection, and safe-area compensation which make them virtually immune from output overload. If adequate heat sinking are provided, these regulators can deliver output currents up to 100mA. The AS78LXX series are available in TO-92 and SOT89-3 packages. AS78LXX Features * * * * * * * Output Current up to 100mA Fixed Output Voltages of 5V, 12V, 15V, 18V and 24V Output Voltage Accuracy of 5% over the Full Temperature Range Internal Short Circuit Current Limiting Internal Thermal Overload Protection No External Components Output Transistor Safe-area Protection Applications * * * Consumer Electronics Microprocessor Power Supply Mother Board TO-92 SOT-89-3 Figure 1.
