Standard Fixed Output LDO Regulator Series
Standard Fixed Output LDO Regulators
BA□□DD0 Series, BA□□CC0 Series
Standard Fixed Output LDO Regulators
with Shutdown Switch
BA□□DD0W and,BA□□CC0W Series
No.10021EBT01
●General
Description
Standard Fixed Output LDO Regulators 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
