TECHNICAL NOTE
3-terminal Regulator & LDO Regulator Series
Standard Fixed Output
LDO Regulator
BA□□DD0,BA□□DD0W,BA□□CC0 and BA□□CC0W Series
●General Description
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.
●Features
1) Maximum output current : 2A (BA□□DD0),
1A(BA□□CC0)
2) ±1% highly accurate output voltage (BA□□DD0)
3)
Low saturation with PNP output
4)
Built-in over-current protection circuit that prevents
the destruction of the IC due to output short circuits
●Applications
Used in DSP power supplies for DVD and CD players, FPDs, televisions, personal computers or any other consumer device
