(1) This device can be used as a low power-loss voltage regulator, applying the voltage exceeding Vo+2.5V to bias input terminal ¢
(VB.)When bias input (VB) is open or less than 0.8V, OFF-state is available.
(VB>=VO+2.5V:output ON, VB=<0.8V or open:output OFF)
(2) It can used as a general regulator with single power supply (dropout voltage : MAX2.5V) by connecting bias input terminal ¢ (VB)
with DC input terminal £.
