ME78L05 V01 Page 1 of 1 General Description Features Pin Configuration Maximum Ratings(Ta=25℃) Parameter Rating Unit Input supply voltage : VIN 30 V MAX. Output current:Iout 100 mA Max Power:Pmax 0.35 W Maximum junction temperature: Tj -25～125 ℃ Storage temperature :Tstr -55～150 ℃ Soldering temperature and time +260（Recommended 10S） ℃ Caution: The absolute maximum ratings are rated values exceeding which the product could suffer physical damage. These values must therefore not be exceeded under any conditions. 3-Terminal Positive Voltage Regulator ME78L05 ME78L05 is three-terminal positive regulators. One of these regulators can deliver up to 100 mA of output current. The internal limiting and thermal -shutdown features of the regulator make them essentially immune to overload. When used as a replacement for a zener diode-resistor Comb- ination, an effective improvement in output impe- dance can be obtained, together with lower quiescent current. ●Output Current of 100mA ●Output Voltages of 5V±5% over the temp- erature range ●Thermal Overload Protection ●Short Circuit Protection ●Output transistor safe area protection ●No external components ●Package：SOT89-3 1.
