LARGE CURRENT POSITIVE
VOLTAGE REGULATORS
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.
CMOS IC
FEATURES
* Maximum Output Current : 400mA
* Maximum Operating Voltage : 8V
* Highly Accurate : ± 2%
* Low Power Consumption : TYP 8.0μA
* Output Voltage Temperature Characteristics : TYP ±100ppm/°C
