The new OMR9601SCK is a 3.3 to 2.5V ultra-low dropout
The new OMR9601SCK is a 3.3 to 2.5V ultra-low dropout linear regulator with 3A capability. The high-current regulator is designed for commercial, scientific and military satellite power systems where point-of-load regulation is required. Applications include power conditioning for digital signal processors (DSP), microcontrollers and microprocessors, low-voltage logic circuits, and field programmable gate array (FPGA) systems.

The new 1MRrad (Si) device was created after extensive ionizing radiation dose rate testing on linear devices under a wide range of electrical, environmental conditions. The device is fully tested and documented under low dose rate symptoms (ELDRS) effect on bipolar linear devices, as well as high dose rate testing including MIL-STD-883, Method 1019, Condition A.

The regulator features a maximum dropout voltage of 0.4V at 3A output and a 0.3V dropout at 1A output. A remote shutdown pin is included, which is useful for power sequencing and other control functions. It is housed in an industry-standard, five-pin TO-258 (MO-78AA), and comes with integrated input and output capacitors. The new regulator is radiation-hardened to 1MRad (Si), and is screened to class K standards as outlined in MIL-PRF-38534.
