Description
The B4250 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
B4250
consists
of
a
high-precision
voltage
reference, an error correction circuit, and a current
limited output driver.
Available in SOT-23 (150mW) and SOT-89 (500mW)
packages minimizing the usage of board real state.
Features
•
Maximum output current: 250 mA.
•
Highly accurate: Output voltage +/- 2%. (1%)
•
CMOS low power consumption.
•
Small input/output differential:
0.38V at 160mA
(Vout=3.3V)
0.12V at 100mA (Vout=5V)
•
Pin-to-Pin Improve XC62FP/XC6201
