300 mA CMOS Low Dropout LDO
B4300
Description
Features
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

CMOS
voltage:
and programmable fuse technologies.
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.
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
