AMC78L05

AMC78L05 www.addmtek.com DESCRIPTION The AMC78L05 is a 3-terminal positive regulator with a fixed output voltage of 5V. Although it is designed as a fixed-voltage regulator, the output voltage can be increased by the use of a simple voltage divider. This regulator can provide local on card regulation, eliminating the distribution problems associated with single point regulation. In addition, it can be used with power-pass elements to make high-current voltage regulators with 100mA output current. Protection features such as thermal shutdown and current limiting have been designed internally which will protect the device from damage in case of overload or overheating. APPLICATIONS Logic Systems Computer Add-On Cards Monitors Power Suppliers 100mA / 3-TERMINAL 5V REGULATOR FEATURES ±5% tolerance of output voltage Wide input range Output current > 100mA Internal thermal overload protection No External Components Short circuit protection Available in 3L plastic TO-92, surface mount SOT-89 and plastic 8 pin S.O.I.C.
