CMOS LDO Regulator Series for Portable Equipments Standard CMOS LDO Regulators BH FB1WG series, BH FB1WHFV series, BH LB1WG series, BH LB1WHFV series Large Current 300mA CMOS LDO Regulators BH MA3WHFV Series No.10020ECT02 Description The BH FB1W, BH LB1W and BH MA3W series are low dropout CMOS regulators with 150 mA and 300 mA output that have 1% high accuracy output voltage. The BH FB1W series combines 40A 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. Features 1) High accuracy output voltage: 1% 2) High ripple rejection ratio: 70 dB (BH FB1WHFV/WG, BH LB1WHFV/WG) 3) Low dropout voltage: 60 mV (when current is 100 mA) (BH MA3WHFV) 4) Stable with ceramic output capacitors 5) Low Bias current : 40A (IO = 50 mA) (BH FB1WHFV/WG) 6) Output voltage ON/OFF control 7) Built-in over-current protection and thermal shutdown circuits 8) Ultra-small power package: HVSOF5 (BH FB1WHFV, BH LB1WHFV) 9) Ultra-small power package: HVSOF6 (BH MA3WHFV) Applications Battery-driven portable devices and etc. Line up 150mA BH FB1W and BH LB1W Series Part Number 1.5 1.8 1.85 2.5 2.8 2.9 3.0 3.1 3.3 Package BH FB1WG - - - SSOP5 BH FB1WHFV - - - HVSOF5 BH LB1WG - - - - - - - SSOP5 BH LB1WHFV - - - - - - HVSOF5 300mA BH MA3WHFV series Part Number 1.5 1.8 2.5 2.8 2.9 3.0 3.1 3.3 Package HVSOF6 BH MA3WHFV Part Number: B H F B 1 W , B H L B 1 W Part Number: B H M A 3 W ab ab ab Symbol Details Symbol Details Output Voltage Designation Output Voltage Designation Output Voltage (V) Output Voltage (V) Output Voltage (V) Output Voltage (V) 15 1.5V (Typ.) 2.9V (Typ.) 15 1.5V (Typ.) 2.9V (Typ.) 29 29 a 18 1.8V (Typ.) 3.0V (Typ.) a 18 1.8V (Typ.) 3.0V (Typ.) 30 30 1J 1.85V (Typ.) 3.1V (Typ.) 25 2.5V (Typ.) 3.1V (Typ.) 31 31 25 2.5V (Typ.) 3.3V (Typ.) 28 2.8V (Typ.) 3.3V (Typ.) 33 33 28 2.8V (Typ.) b Package: HFV : HVSOF6 b Package: G : SSOP5 HFV : HVSOF5 www.rohm.com 1/8 2010.07 - Rev.
