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 40µA 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 : 40µA (I
O
= 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.

A difficult problem for beginners: using optocouplers instead of push switches.
The original circuit is: +5V is connected to the 13th and 11th pins of the inverter HC04 through two buttons. Now we need to use an optocoupler to replace the button switch. Since the two optocouplers...
