DESCRIPTION

The LX8382/8382A series ICs are positive regulators designed to provide 10A output current. All internal circuitry is designed to operate down to a 1V input-to-output differential, so the LX8382/82A can operate with greater efficiency than previously available devices. The dropout voltage for each product is fully specified as a function of load current. Dropout is guaranteed at a maximum of 1.4V for the LX8382 and 1.2V for the LX8382A at maximum output current, decreasing at lower load currents. Fixed versions are also available and specified in the Available Options table below. The LX8382/82A have 1 initial voltage reference accuracy and 2 over line, load and temperature.

The LX8382/82A series devices are pin-compatible with earlier 3-terminal regulators, such as the 117 series products. While a 10µF output capacitor is required on both input and output of these new devices, this capacitor is generally included in most regulator designs.

LX8382A-33CP属于集成电路（IC） > 稳压器 - 线性。美高森美公司制造生产的LX8382A-33CP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。
