Description
The B4150 series are a group of positive output voltage,
five-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 B4150 consists of a high-precision voltage
reference, an error correction circuit, and a current
limited output driver. Key features include a Shutdown
Pin that reduces supply current to 0.5µA max and a
470pF Bypass input to ground reduces noise present on
the internal reference, which in turn significantly reduce
output noise. If output noise is not concern, this input
maybe left unconnected. Larger capacitor values cap be
used, but results in longer time period to rated output
voltage when power initially applied.
The ON/OFF pin enables the output to be turned off,
resulting in reduced power consumption. Provided in
SOT-25 (150mW) packages minimizes the usage of
board real state.
