300mA Variable / Fixed Output
LDO Regulators
BDxxHA3WEFJ
●General Description
BDxxHA3WEFJ series devices are LDO regulators with an output current of 0.3A. 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 1.5 to 7.0V using external resistors. Various fixed output voltage devices that do not use external
resistors are also 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.
