NCP4623中文资料NCP4623: Linear Voltage Regulator, LDO, Wide Voltage Input, 150 mA数据手册ONSEMI规格书

描述 Description

The NCP4623 is a CMOS Linear voltage regulator designed for wide input voltage range. The maximum operating input voltage is up to 24 V with a minimum voltage starting from 2 V. The Chip Enable pin allows the device to lower the standby current to 0.1 uA typ. The NCP4623 features many protections for any current or thermal sensitive devices with current fold-back protection, thermal shutdown protection, and peak and short current protection. This device is available in adjustable and fixed voltage output with 0.1 V steps. They are available in very thin XDFN6 1.6 x 1.6 x 0.4 mm in size and the very popular SOT23-5 and SOT89-5 packages. Please contact your local sales office for additional output voltage options.

简介

NCP4623属于集成电路（IC）的线性+开关稳压器。由制造生产的NCP4623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。
