UNISONIC TECHNOLOGIES CO., LTD UT10XX CMOS IC THREE-TERMINAL LOW POWER VOLTAGE REGULATORS DESCRIPTION The UTC UT10XX series is a set of three-Terminal low power voltage regulators implemented in CMOS technology. They are available with several fixed output voltages ranging from 1.5V~7.0V. The advantage of CMOS technology is low voltage dropout and low quiescent current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain variable voltages and currents. FEATURES * Low power consumption * Low voltage dropout * Low temperature coefficient * Wide operating voltage (12V Max.)
