Product Description
The LM1114 series is a group of positive voltage output, three-pin regulators, that provide a
high current even when the input/output voltage differential is small. Low power consumption
and high accuracy is achieved through CMOS and programmable fuse technologies. Output
voltage: 2V to 6V in 0.1V increments.
The LM1114 consists of a high-precision voltage reference, an error correction circuit, and a
current limited output driver. Transient response to load variations is improved in comparison
to the existing ones.
