Part Number : B4600CR-5.9
Function : 600mA, Low Dropout Voltage Regulator
Package : SOT-89, SOT-223 Type
Maker : Bay Linear
Pinouts : 
Description :
The B4600CR-5.9, B4600 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 B4600 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.
