NCP59748中文资料Ultra-Low Dropout Voltage Regulator with Bias Rail, 1.5A数据手册ONSEMI规格书

描述 Description

NCP59748 is an Ultra-Low Dropout Voltage Regulator,
capable of providing an output current in excess of 1.5 A with a
dropout voltage of 60 mV typ. at full load current. The devices are
stable with ceramic and any other type of output capacitor ≥ 2.2 µF.
This series contains adjustable output voltage version with output
voltage down to 0.8 V. Internal protection features consist of built-in
thermal shutdown and output current limiting protection.
User-programmable Soft-Start and Power-Good pins are available on
both QFN and DFN versions.
The NCP59748 is offered in DFN10 3×3 and QFN20 5×5 packages.

简介

NCP59748属于集成电路（IC）的线性+开关稳压器。由制造生产的NCP59748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。
