BH ŜŜ MA3WHFV Series
No.10020ECT02
Description
The BHŜŜFB1W, BHŜŜLB1W and BHŜŜMA3W series are low dropout CMOS regulators with 150 mA and 300 mA
output that have ±1% high accuracy output voltage.
The BHŜŜFB1W 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 (BHŜŜFB1WHFV/WG, BHŜŜLB1WHFV/WG)
3) Low dropout voltage: 60 mV (when current is 100 mA) (BHŜŜMA3WHFV)
4) Stable with ceramic output capacitors
5) Low Bias current : 40µA (IO = 50 mA) (BHŜŜFB1WHFV/WG)
6) Output voltage ON/OFF control
7) Built-in over-current protection and thermal shutdown circuits
8) Ultra-small power package: HVSOF5 (BHŜŜFB1WHFV, BHŜŜLB1WHFV)
9) Ultra-small power package: HVSOF6 (BHŜŜMA3WHFV)
Applications
Battery-driven portable devices and etc.
