Preliminary Information |
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 2 A 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.
Features
•Maximum Output Current: 500 mA.
•Highly accurate: Output voltage +/- 2%.
•Only 2 A power Consumption.
•Very Low Dropout:
0.11V @ 100mA
0.3V @ 300mA
0.5V @ 450mA
•Offered in SOT-89 & SOT-223 Packages
Applications
•Battery Powered Equipment
•Notebook PC, Palmtops, PDA
•Portable Cameras and Video Recorders
•Reference Voltage Sources
