UTC UNISONIC TECHNOLOGIES CO., LTD. 1

QW-R102-003,A

3~8 AMP 5V TO 3.3V VOLTAGE
CONVERSION REGULATOR

DESCRIPTION

The UTC U584/585/587 voltage regulators are monolithic
integrated circuits, designed for use in applications requiring a
well regulated positive output voltage with +5V input. The
output voltage can be adjustable from 3.8 V down to 1.3V.

FEATURES

*Low dropout performance.
*Adjustable output down to 1.3V.
*Line regulation typically below 0.1%.
*Load regulation typically below 0.1%.
*Output current can be up to 8 A for UTC U584.
