Automotive 1.0A Variable Output LDO Regulator - …

1 Datasheet Automotive Variable Output LDO Regulator BDxxIC0 MEFJ-M. General Description BDxxIC0 MEFJ-M is a LDO Regulator with Output current The Output accuracy is 1% of Output voltage. With external resistance, it is available to set the Output voltage at random (from to ).It has package type: HTSOP-J8. Over current protection (for protecting the IC destruction by Output short circuit), circuit current ON/OFF switch (for setting the circuit 0 A at shutdown mode), and thermal shutdown circuit (for protecting IC from heat destruction by over load condition). are all built in. It is usable for ceramic capacitor and enables to improve smaller set and long-life. Features Package (Typ.) (Typ.) (Max.). High accuracy reference voltage circuit HTSOP-J8 x x Built-in Over Current protection circuit (OCP).
