- • 5.0V, 6.2V and 8.0V Output Voltage Available* •• Battery Powered Systems
- • Output Voltage Tolerance of ±±5% Over Temperature •• Portable Consumer Equipment
- • Output Current in excess of 100mA •• Cordless Telephones
- • Internal Thermal Overload Protection •• Portable (Notebook) Computers
- • Overvoltage Protection •• Portable Instrumentation
- • Short Circuit protection •• Radio Control Systems
- • TO-92, SO-8 and SOT-89 Packages Available •• 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 T A = T J = 25 °C. Note 4: The junction-to-ambient thermal resistance are as follows: 195 °C/W for the TO-92 (N) package, 160 °C/W for the molded plastic SO-8 (S), 150 °C/W for the SOT-89 package.
