BA12ST集成电路（IC）的线性+开关稳压器规格书PDF中文资料

BA12ST属于集成电路（IC）的线性+开关稳压器。由罗姆半导体集团制造生产的BA12ST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。

The BAOOST series are variable, fixed output low drop-out type voltage regulators with an ON / OFF switch. These regulators are used to provide a stabilized output voltage from a fluctuating DC input voltage.

Fixed output voltages are 3V∗, 3.3V, 5V, 6V∗ 7V, 8V, 9V, 10V, 12V, and 15V∗. The maximum current capacity is 1A for each of the above voltages. (Items marked with an asterisk are under development.)

特性 Features

1) Built-in overvoltage protection circuit, overcurrent protection circuit and thermal shutdown circuit.

2) TO220FP-5 package can be used in wide range of applications.

3) 0µA (design value) circuit current when switch is off.

4) Richly diverse lineup.

5) Low minimum I / O voltage differential.
