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. +0.10 0.55 -0.05 0.100.10 2.300.10 4.600.10 SP-3SU Note) The package of this product will be changed to lead-free type (SP-3SUA).
