Standard LDO Regulators

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

●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

No.11021ECT01
