Product Description
The LM1114B 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.
The LM1114B 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.
