AN78xxNSP Series
3-pin positive output
voltage regulator (1 A type)
I Overview
The AN78xxNSP 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 1 A.
