描述 Description

The NCV4266−2C is a 150 mA output current integrated low dropout, low quiescent current regulator family designed for use in harsh automotive environments. It includes wide operating temperature and input voltage ranges. The device is offered with fixed voltage versions of 3.3 V and 5.0 V available in 2% output voltage accuracy. It has a high peak input voltage tolerance and reverse input voltage protection. It also provides overcurrent protection, overtemperature protection and enable function for control of the state of the output voltage. The NCV4266−2C is available in SOT−223 surface mount package. The output is stable over a wide output capacitance and ESR range. The NCV4266−2C has improved startup behavior during input voltage transients.

简介

NCV4266-2C属于集成电路（IC）的线性+开关稳压器。由制造生产的NCV4266-2C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。
