MC7905A中文资料MC7905A: Linear Voltage Regulator, Negative, 5.0 V, 1.0 A数据手册ONSEMI规格书

描述 Description

The MC7900 fixed output negative linear voltage regulator is intended as a complement to the popular MC7800 series devices. This negative voltage regulator is available in the same seven-voltage options as the MC7800 devices. In addition, one extra voltage option commonly employed in MECL systems is also available in the negative MC7900 series. Available in fixed output voltage options from -5.0 V to -24 V, these linear voltage regulators employ current limiting, thermal shutdown and safe-area compensation - making them remarkably rugged under most operating conditions. With adequate heatsinking they can deliver output currents in excess of 1.0 A.

简介

MC7905A属于集成电路（IC）的线性+开关稳压器。由ONSEMI制造生产的MC7905A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。
