CMOS IC
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.
FEATURES
* Maximum Output Current : 400mA * Maximum Operating Voltage : 8V * Highly Accurate : ± 2%
* Low Power Consumption : TYP 8.0 µA
* Output Voltage Temperature Characteristics : TYP ±100ppm/°C
*Pb-free plating product number: LR1106L
