DESCRIPTION

This three terminal positive regulator is supplied in a hermetically sealed metal

surface mount package. All protective features are designed into the circuit, including

thermal shutdown, current limiting and safe-area control. With heat sinking, they can

deliver over 1.0 amp of output current. This unit features output voltages that can be

trimmed using external resistors, from 1.2 volts to 37 volts.
