Description
The B4250 series are a group of positive output voltage,
three-pin r egulators, which pr ovide a high current eve n
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
Applications
• Battery Powered Equipment
• Notebook PC, Palmtops, PDA
• Portable Cameras and Video Recorders
• Reference Voltage Sources
