NCP4625数据手册集成电路（IC）的线性+开关稳压器规格书PDF

描述 Description

The NCP4625 is a CMOS Linear voltage regulator with 300 mA output current capability. The device is capable of operating with input voltages up to 10 V, with high output voltage accuracy and a low temperature drift coefficient. The NCP4625 is easy to use, with output current foldback protection and a thermal shutdown circuit included. A Chip Enable function is included to save power by lowering supply current. Output voltages are available in 100mV steps between 1.2V and 6.0V. The device comes in a choice of three packages: SC70-5, SOT23-5 and SOT89-5, and is available in two output configurations: standard output or auto-discharge. Contact your local sales representative for a specific voltage, package and output configuration.

简介

NCP4625属于集成电路（IC）的线性+开关稳压器。由制造生产的NCP4625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。
