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 1.5 amp of output current. This unit features output voltages that can be
trimmed using external resistors, from 1.2 volts to 57 volts.
