NCV4276C中文资料Linear Voltage Regulator, Low-Dropout (LDO), 400 mA数据手册ONSEMI规格书

描述 Description

The NCV4276C is a 400 mA output current integrated low-dropout (LDO)
regulator family designed for use in harsh automotive environments.
It includes wide operating temperature and input voltage ranges. The
device is offered with 3.3 V, 5.0 V, and adjustable voltage versions
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
inhibit for control of the state of the output voltage. The NCV4276C
family is available in DPAK and D2PAK surface mount packages.
The output is stable over a wide output capacitance and ESR range.
The NCV4276C has improved startup behavior during input voltage
transients.

简介

NCV4276C属于集成电路（IC）的线性+开关稳压器。由制造生产的NCV4276C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。
