... Stabilized fixed output voltage is obtained from unstable DC input voltage with using mini-mum external components. 9 types of fixed output volt-age are available 15V and 18 V. They can be used widely in power circuits with current capacity up to 500 mA. The AN78M12NSP is the 12 V output voltage type in these series. Features Built-in overcurrent limit circuit ...
