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.
