NCP4632中文资料NCP4632: Linear Voltage Regulator, LDO, Low Voltage, 3.0 A, with Reverse Current Protection数据手册ONSEMI规格书

描述 Description

The NCP4632 is a CMOS Low Dropout, Linear voltage regulator with high output current capability (up to 3 A). This device can provide output voltages as low as 0.8 V while maintaining a low dropout voltage of 510 mV typ. at full load. The NCP4632 is designed to draw only 350 uA of supply current and less than 1 uA in standby mode to minimize current consumption for battery operated applications. The device has a high accuracy output voltage of ±1% along with soft start and reverse current protection circuits to protect the device and the application. The NCP4632 is available in a Pb Free DPAK5 package in both fixed and adjustable output voltage options. The output voltage for the fixed options can be modified in 0.1 V steps from 0.8 V to 4.2 V Please contact your sales office for any additional fixed voltage outputs to those already listed.

简介

NCP4632属于集成电路（IC）的线性+开关稳压器。由ONSEMI制造生产的NCP4632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。
