300mA Variable / Fixed Output
LDO Regulators
BDxxGA3WEFJ / BDxxGA3WNUX
●General
Description
BDxxGA3WEFJ / BDxxGA3WNUX series devices are LDO regulators with an output current of 300mA. 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 1.5V to 13V 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 small package types : HTSOP-J8 (4.90mm x 6.00mm x 1.00mm) / VSON008X2030 (2.00mm x 3.00mm x 0.60mm).
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 thermal over-load conditions. These LDO regulators are usable with
ceramic capacitors that enable a smaller layout and longer life.
