LDO Regulator

BA□□DD0,BA□□DD0W,BA□□CC0 and BA□□CC0W Series

●General Description

●Features

●Applications

●Line up

Used in DSP power supplies for DVD and CD players, FPDs, televisions, personal computers or any other consumer device

Part Number

BA□□DD0/CC0 are low-saturation regulators, available for output s up to 2A/1A. ROHM has a wide output voltage range

and package lineup with and without shutdown switches. This IC has a built-in over-current protection circuit that prevents

the destruction of the IC due to output short circuits, a thermal shut-down circuit that protects the IC from damage due to

overloading and an over-voltage protection circuit that protects the IC from surges generated in the power supply line of the

IC.
