Each of these ICs consists of a voltage reference unit, an error amplifier, resistors for setting output voltage and a current limit circuit. The output voltage of these ICs is fixed with high accuracy. Even if VOUT is shorted to GND, the included current limit circuit protects the ICs from the destruction. Furthermore, these ICs have a chip enable function, so that the supply current on standby can be minimized. Since the package for these ICs are SC-82AB(Super Mini-mold)package, high density mounting of the ICs on boards is possible.
