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
5) Built-in thermal shutdown circuit for protecting the
IC from damage due to overloading
6) Built-in over- voltage protection circuit that prevents
the destruction of the IC due to power supply
surges
7) TO220FP and HRP5 packaging (BA□□DD0)
TO220FP and TO252 packaging(BA□□CC0)
●Applications
Used in DSP power supplies for DVD and CD players, FPDs, televisions, personal computers or any other consumer device

When using at temperatures over Ta=25℃, please refer to the heat reducing characteristics shown in Fig.29 through 31. The IC
characteristics are closely related to the temperature at which the IC is used and if the temperature exceeds the maximum
junction temperature Tj
MAX
., the elements may be damaged or destroyed. From the standpoints of instantaneous destruction and
long-term operating reliability, it is necessary give sufficient consideration to IC heat. In order to protect the IC from thermal
damage, it is necessary to operate it at temperatures lower than the maximum junction temperature Tj
MAX
of the IC.
