NCV4294C中文资料Linear Voltage Regulator, LDO, 30 mA数据手册ONSEMI规格书

描述 Description

The NCV4294C is a monolithic integrated low dropout voltage regulator with an output current capability of 30 mA available in the TSOP–5 package. The output voltage is accurate within ±4.0% with a maximum dropout voltage of 250 mV with an input up to 45 V. Low quiescent current is a feature typically drawing only 160 µA with a 1 mA load. This part is ideal for automotive and all battery operated microprocessor equipment. The regulator is protected against reverse battery, short circuit and thermal overload conditions.

简介

NCV4294C属于集成电路（IC）的线性+开关稳压器。由ONSEMI制造生产的NCV4294C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。
