LARGE CURRENT POSITIVE VOLTAGE REGULATORS
3 2 1
CMOS IC
DESCRIPTION
The UTC LR1106 series are positive voltage regulators that developed in CMOS technology with highly precise, low power consumption. It is capable of large currents with a significantly small dropout voltage. The device consists of a driver transistor, a precision reference voltage and an error amplifier. Basically, output voltage is selectable in 0.1V step form 1.8V to 6.0V, 2.85V also is available.
