AN78MxxNSP Series
3-pin positive output voltage
regulator (500 mA type)
I Overview
The AN78MxxNSP series is a 3-pin fixed positive output type monolithic voltage
regulator housed in surface mounting package. Stabilized fixed output voltage is obtained from unstable DC input voltage with using minimum external components. 9 types of fixed output voltage are available; 5 V, 6 V, 7 V, 8 V, 9 V, 10 V, 12 V, 15 V and 18 V. They can be used widely in power circuits with current capacity up to 500 mA.
