2A/1A Variable Output
LDO Regulators
BA00DD0xx series BA00CC0xx series
●General
Description
The BA00DD0xx and BD00CC0xx 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% high-precision output voltage (BA00DD0xx)
Low saturation with PNP output
Built-in over-current protection circuit that prevents
the destruction of the IC due to output short circuits
Built-in thermal shutdown circuit for protecting the IC
from thermal damage due to overloading
Built-in over- voltage protection circuit that prevents
the destruction of the IC due to power supply surges
