NCV7808B集成电路（IC）的线性+开关稳压器规格书PDF中文资料

NCV7808B属于集成电路（IC）的线性+开关稳压器。由安森美半导体制造生产的NCV7808B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。

These voltage regulators are monolithic integrated circuits designed

as fixedïvoltage regulators for a wide variety of applications

including local, onïcard regulation. These regulators employ internal

current limiting, thermal shutdown, and safeïarea compensation. With

adequate heatsinking they can deliver output currents in excess of

1.0 A. Although designed primarily as a fixed voltage regulator, these

devices can be used with external components to obtain adjustable

voltages and currents.
