Description

The 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.

Features

• Maximum Output Current: 600 mA.

• Highly accurate: Output voltage +/- 2.5%.

• 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
