NCV4250-2C中文资料Linear Voltage Regulator, Tracking, 50 mA, with Enable数据手册ONSEMI规格书

描述 Description

The NCV4250−2C is a monolithic integrated low dropout tracking
voltage regulator designed to provide a buffered output voltage that
closely tracks the reference input voltage. The part can be used in
automotive applications with remote sensors or any situation where
it is necessary to isolate the output of the other regulator. The
NCV4250−2C also enables the user to bestow a quick upgrade to
their module when added current is needed and the existing regulator
cannot provide.

特性 Features

• Up to 50 mA Source Capability
• Capability to power sensors external to the automotive module.

简介

NCV4250-2C属于集成电路（IC）的线性+开关稳压器。由制造生产的NCV4250-2C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。
