1A Variable / Fixed Output
LDO Regulators
BDxxIC0WEFJ / BDxxIC0WHFV
●General
Description
BDxxIC0W series devices are LDO regulators with an output current of 1.0A. The output accuracy is ±1% of the output
voltage. Both fixed and variable output voltage devices are available. The output voltage of the variable output voltage
device can be varied from 0.8 to 4.5V using external resistors. Various fixed output voltage devices that do not use external
resistors are also available. These LDO regulators are available in two package types: HTSOP-J8 (4.90mm x 6.00mm x
1.00mm) and HVSOF6 (1.60mm x 3.00mm x 0.75mm), and can be used in a wide variety of digital appliances. 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.
