Linear Voltage Regulators


API Technologies designs and manufactures a wide range of space-qualified, rad-hard linear regulators qualified for space. Product lines include positive and negative linear voltage regulators (and voltage references) at up to 1.5 amps output.

Models in this product series offer quiet, linear voltage regulation with stabilities over the full temperature range approaching that of a very stable voltage reference. Features include both adjustable and fixed outputs with remote sense capability, as well as excellent power supply rejection ratios. In addition, there is an option to include a resistor to limit output voltage rise should the remote sense connection be severed.
