NCV662数据手册集成电路（IC）的线性+开关稳压器规格书PDF

描述 Description

This series of Low Quiescent Current Low Dropout (LDO) Linear Voltage Regulators initially designed for handheld communication equipment and portable battery powered applications can be used in automotive application requiring ultra low quiescent current. It should be used as post regulation device as the product is not protected against high input transient voltages inherent to automotive battery operation.This series features an ultra-low quiescent current of 2.5µA as well as an Enable pin that allows to decrease the current consumption down to 0.1µA typical. Each device contains a voltage reference unit, an error amplifier, a PMOS power transistor, resistors for setting output voltage, and protections such as current limit and temperature limit circuits. The NCV662 LDO Linear Voltage Regulator has been designed to be used with low cost ceramic capacitors and requires a minimum output capacitor of 0.1 µF. The device is housed in the micro-miniature SC82-AB surface mount package. Pb-free plating options are available.Standard voltage versions are 1.5, 1.8, 2.5, 2.7, 2.8, 3.0, 3.3, and 5.0 V.

简介

NCV662属于集成电路（IC）的线性+开关稳压器。由制造生产的NCV662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。
