The space-saving SOT23 package is attractive for ²Pocket² and ²Hand Held² applications. The devices are capable of supplying 300mA of output current continuously. They are available with several fixed output voltages ranging from 1.8V to 5.0V. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain variable voltages and currents. These rugged devices have Thermal Shutdown and Current Limiting to prevent device failure under the ²Worst² of operating conditions.
