1A Fixed Output
LDO Regulators
BDxxHC0WEFJ
●General
Description
BDxxHC0WEFJ series devices are LDO regulators with an output current of 1.0A. The output accuracy is ±1% of the output
voltage. Various fixed output voltage devices that do not use external resistors are available. It can be used for a wide
range of digital appliance applications. It has a small package type: HTSOP-J8 (4.90mm x 6.00mm x 1.00mm). These
devices have built in over current protection to protect the device when output is shorted, 0µA shutdown mode and thermal
shutdown circuit to protect the device during over load conditions. These LDO regulators are usable with ceramic capacitors
that enable a smaller layout and longer life.
