Advanced Monolithic Systems AMS78LXX 100mA VOLTAGE REGULATOR FEATURES APPLICATIONS * 5.0V, 6.2V and 8.0V Output Voltage Available* * Output Voltage Tolerance of 5% Over Temperature * Output Current in excess of 100mA * Internal Thermal Overload Protection * Overvoltage Protection * Short Circuit protection * TO-92, SO-8 and SOT-89 Packages Available * Battery Powered Systems * Portable Consumer Equipment * Cordless Telephones * Portable (Notebook) Computers * Portable Instrumentation * Radio Control Systems * Logic Systems GENERAL DESCRIPTION The AMS78LXX series consists of positive fixed voltage regulators ideally suited for use in battery-powered systems. These devices feature very low quiescent current of 1mA or less when supplying 10mA loads. This unique characteristic and the low input -output differential of less than 1V required for proper regulation, make the AMS78LXX ideal to use for standby power systems and portable equipment. The AMS78LXX series also includes internal current limiting, over voltage protection, thermal shutdown, and is able to withstand temporary power-up with mirror-image insertion. The AMS78LXX series is offered in the 3-pin TO-92 package, 8-pin plastic SOIC and SOT-89 packages.

For guaranteed performance limits and associated test conditions, see the Electrical Characteristics tables. Note 2: See Circuit in Typical Applications. To ensure constant junction temperature, low duty cycle pulse testing is used. Note 3: Limits appearing in boldface type apply over the entire junction temperature range for operation. Limits appearing in normal type apply for TA = TJ = 25C. Note 4: The junction-to-ambient thermal resistance are as follows: 195C/W for the TO-92 (N) package, 160C/W for the molded plastic SO-8 (S), 150C/W for the SOT-89 package.
