CMOS LDO Regulators

BH ŜŜ MA3WHFV Series

Description

The BHŜŜFB1W, BHŜŜLB1W and BHŜŜMA3W series are low dropout CMOS regulators with 150 mA and 300 mA
output that have
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 (I

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.
