Inspire the Linear Power

250 mA CMOS Low Dropout LDO

B4250

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

Applications

•Battery Powered Equipment

•Notebook PC, Palmtops, PDA

•Portable Cameras and Video Recorders

•Reference Voltage Sources
