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 (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.

BH28FB1WHFV属于集成电路（IC） > 线性 + 开关稳压器。罗姆半导体集团制造生产的BH28FB1WHFV稳压器 - 线性线性稳压器用于提供稳定的输出电压，无论负载电流、输入电压或环境因素如何变化，这些输出电压通常都要保持不变。它们的工作原理要求输入电压维持在高于所需的输出电压，而且要超出某个最小量，并且在工作时会将输入端的任何多余电压转换为热量。对于大多数应用而言，虽然这种稳压器的效率低于开关模式的稳压器，但它们通常更适合对噪声高度敏感的应用。
