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.
