BD18IA5WEFJ-E2 ROHM

Datasheet 500mA Variable / Fixed Output LDO Regulators BDxxIA5WEFJ General Description BDxxIA5WEFJ series devices are LDO regulators with an output current of 0.5A. 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. 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, 0A 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. Features Package (Typ.) (Typ.)
