300 mA CMOS Low Dropout LDO		B4300

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
