Description

The B4300 series are a group of positive output voltage,
three-pin regulators, which provide a high current even
when the input/output voltage differential is small. Low
power consumption and high accuracy is achieved
though CMOS and programmable fuse technologies.
Output voltage: 2.0V to 6.0V in 0.1V increments.

The B4300 consists of a high-precision voltage
reference, an error correction circuit, and a current
limited output driver.

Available in SOT-89 (300mW), and SOT-223 (500mW)
packages minimizing the usage of board real state.

Features

• Maximum output current: 300 mA.

• Highly accurate: Output voltage +/- 1.4%

• Extremely Low Ground Current 6µA

• CMOS low power consumption.

• Over-Current & Over-Temp. Protection

• Small input/output differential:

0.3V @ 300mA

0.1V @ 100mA

• Pin-to-Pin replacement for TC1108 & XC6203

• Offered in SOT-89 & SOT-223

Applications

• Battery Powered Equipment

• Notebook PC, Palmtops, PDA

• Portable Cameras and Video Recorders

• Reference Voltage Sources
