DESCRIPTION
This 3.3 volt fixed voltage regulator is designed to provide 1.3A of current with a higher
efficiency than conventional voltage regulators. This device is designed to operate down to 1
volt input to output differential and the 1.5V dropout voltage is guaranteed at the maximum
output current. This device is ideally suited for those systems where high reliability, small size
and low weight are required. The isolated package simplifies the system assembly methods.
