B4500
Preliminary Information
Description
Features
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.
• Maximum Output Current: 500 mA.
• Highly accurate: Output voltage +/- 2%.
• Only 2µA 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
