MC79M数据手册集成电路（IC）的线性+开关稳压器规格书PDF

描述 Description

The MC79M00 Negative Linear Voltage Regulator is intended as a complement to the popular MC78M00 series devices. Available in fixed output voltage options of -5.0, -8.0, -12 and -15 V, this Negative Linear Voltage Regulator employs current limiting, thermal shutdown and safe-area compensation - making it remarkably rugged under most operating conditions. With adequate heatsinking, it can deliver output currents in excess of 0.5 A.

简介

MC79M属于集成电路（IC）的线性+开关稳压器。由制造生产的MC79M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。
