The OMR9601SCK linear regulator features a maximum dropout voltage of 0.4V at a 3A output and a 0.3V dropout at a 1A output in high radiation environments. The regulator also features a remote shutdown that is said to be useful for power sequencing and other control functions. The low-dropout regulator is housed in a five-pin TO-258 package and comes with integrated input and output capacitors. And it is radiation-hardened to 1 MRad and is screened to class K standards as outlined in MIL-PRF-38534.
