Description

The B4500 series are a group of positive output voltage, three-pin regulators, that provide a high current even when the input/output voltage differential is small. Very low power consumption, only 2µA typ., and high accuracy is achieved though CMOS construction and programmable fuse technologies. Output voltage:  2.0V to 6.0V in 0.1V increments.
 
The B4500 consists of a high-precision voltage reference, an error correction circuit, and a current limited output driver.
 
Available in SOT223 (500mW) and SOT-89 (300mW) packages minimizing the usage of board real state.
