DESCRIPTION

The LX8383/8383A/8383B series ICs are positive regulators designed to provide 7.5A output current. All internal circuitry is designed to operate down to a 1V in put-to-output differential, so the LX8383/83A/83B can operate with greater efficiency than previously available devices.

LX8383-00属于集成电路（IC） > 稳压器 - 线性。美高森美公司制造生产的LX8383-00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。
