●Description

The BA00DD0/CC0 series are low-saturation regulators available for outputs up to 2A/1A. The output voltage can be
arbitrarily configured using the external resistance. These series of LDO regulators are offered in a broad packaging lineup.
This IC has a built-in over-current protection circuit that prevents the destruction of the IC due to output short circuits and a
thermal shutdown circuit that protects the IC from thermal damage due to overloading.

●Features

1) Maximum output current: 2A (BA00DD0 series), 1A(BA00CC0 series)

2) ±1% high-precision output voltage (BA00DD0)

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 thermal 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 andHRP5 packaging (BA00DD0), and TO220FP and TO252 packaging (BA00CC0)

●Applications

Usable in DSP power supplies for DVDs and CDs, FPDs, televisions, personal computers or any other consumer device
