The OMR183-186 series are radiation-tolerant, low-dropout positive adjustable voltage regulators available in hermetic packages. They operate down to 1V dropout and feature 0.015% line regulation, 0.1% load regulation, and a 1% reference voltage.

Key Features

These devices are designed for high-reliability applications, such as space systems, where small size, high reliability, and radiation tolerance are crucial. They are pin-compatible with older three-terminal regulators and offer high efficiency.

Electrical Characteristics

The series includes devices with output currents of 7.5A, 5A, 3A, and 1.5A, with a maximum operating junction temperature range of -55°C to 150°C. They have a high level of radiation tolerance, with total dose ratings of 100k Rad (Si) for OMR183 and OMR184, 50k Rad (Si) for OMR185, and 30k Rad (Si) for OMR186.

The devices are available in various packages, including TO-257, TO-258, SMD-1, and TO-205, and are screened to MIL-STD-883 standards.
