TSZ22111 14 001 Variable / Fixed Output LDO Regulators BDxxHA3 WEFJ General Description BDxxHA3 WEFJ series devices are LDO Regulators with an Output current of 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 to using external resistors.
2 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 ( x x ). These devices have built in over current protection to protect the device when Output is shorted, 0 A 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.
