The BH

FB1W, BH

LB1W and BH

MA3W series are low dropout CMOS regulators with 150 mA and 300 mA

output that have

The BH

FB1W series combines 40

µA low current consumption and a 70 dB high ripple rejection ratio by utilizing output

level CMOS technology. The components can be easily mounted into the small standard SSOP5 and the ultra-small

HVSOF5/HVSOF6 packages.
