All rights reserved. 2A/ 1a variable output ldo regulators BA00DD0XX series BA00CC0XX series General Description The BA00DD0XX and BA00CC0XX 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.
