B4151
Description
Features
The B4151 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 B4151 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. With good transient
responses, output remains stable even during load
changes.
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.
• Maximum output current: 150 mA.
• Highly accurate: Output voltage +/- 2%(1%)
