NCP5663中文资料Linear Voltage Regulator, LDO, Fast Response, 3.0 A, with Enable数据手册ONSEMI规格书

描述 Description

The NCP5663 is a high performance, low dropout (LDO) linear voltage regulator designed for high power applications that require up to 3.0 A current. It is offered in both fixed and adjustable output versions. With output voltages as low as 0.9 V and ultra-fast response times for load transients, the NCP5663 also provides additional features such as Enable and Error Flag (for the fixed output version), increasing the utility of this device. A thermally robust, 5 pin D2Pak, combined with an architecture that offers low ground current (independent of load), provides for a superior high-current LDO solution.

特性 Features

• UltraFast Transient Response (Settling Time: 1 - 3 us)
• Low Noise Without Bypass Capacitor (28 uVrms)
• Low Ground Current Independent of Load (3.0 mA Maximum)
• Fixed/Adjustable Output Voltage Versions
• Enable Function
• Error Flag (Fixed Output Version)
• Current Limit Protection
• Thermal Protection
• 0.9 V Reference Voltage for UltraLow Output Operation
• Power Supply Rejection Ratio > 65 dB

应用 Application

• Networking Equipment
• Servers
• Game Boxes
• Set Top Boxes

简介

NCP5663属于集成电路（IC）的线性+开关稳压器。由制造生产的NCP5663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。
