BA90DD0T集成电路（IC）的线性+开关稳压器规格书PDF中文资料

BA90DD0T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BA90DD0T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。

General Description

Standard Fixed Output LDO Regulators are low-saturation regulators, available for output s up to 2A / 1A. ROHM has a wide output voltage range and package lineup with and without shutdown switches. This IC has a built-in over-current protection circuit that prevents the destruction of the IC due to output short circuits, a thermal shut-down circuit that protects the IC from damage due to overloading and an over-voltage protection circuit that protects the IC from surges generated in the power supply line of the IC.

特性 Features

■ ± 1 highly accurate output voltage (BAxxDD0xx)

■ Low saturation with PNP output

■ Built-in over-current protection circuit that prevents the destruction of the IC due to output short circuits

■ Built-in thermal shutdown circuit for protecting the IC from damage due to overloading

■ Built-in over- voltage protection circuit that prevents the destruction of the IC due to power supply surges

Applications

Used in DSP power supplies for DVD and CD players, FPDs, televisions, personal computers or any other consumer device
