MC79L12中文资料MC79L12: Linear Voltage Regulator, Negative, 12 V, 100 mA数据手册ONSEMI规格书

描述 Description

The MC79L00 negative linear voltage regulator is an inexpensive, easy-to-use device suitable for numerous applications requiring up to100 mA. Like the higher powered MC7900 Series negative regulators, this linear voltage regulator features thermal shutdown and current limiting, making it remarkably rugged. In most applications, no external components are required for operation.The MC79L00 linear voltage regulator is useful for on-card regulation or any other application where a regulated negative voltage at a modest current level is needed. This regulator offers substantial advantages over the common resistor/zener diode approach.

简介

MC79L12属于集成电路（IC）的线性+开关稳压器。由制造生产的MC79L12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。
